Top Uses for Thermal Imaging in Law Enforcement

It should not be surprising that advance technologies like thermal imaging could be useful in the hands of law enforcement where the enforcement officers are able to view or detect specific images which the naked eye cannot. Now a day thermal imaging in law enforcement agencies plays a great role.

Benefits of Thermal Imaging

Thermal imaging enhances law enforcement officers’ effectiveness in managing surveillance activities or helps locate suspects for a quick apprehension. Crime scenes could be investigated thoroughly for clear clues and evidence in solving the mystery while search and rescue operations could be executed successfully through clear directions on search.

Moreover, such technology empowers law enforcement officers the ability to detect and avoid potential dangers to stay safe while carrying out their missions. Thermal imagers offer a stronger light intensification for a clearer view even at night. The environment is lighted appropriately through an amplification of light while detecting heat or long wave infrared light.

Thermal technology is widely used in many areas that benefit law enforcement.

1. Fugitive Searches

Fugitive SearchesLaw enforcement officers manipulate thermal imagers to view dark or camouflaged suspects with a clear distinction from the surroundings. The thermal imager displays the suspect’s body heat even in concealed position for a more accurate arrest.
Thermal imagers are more effective than flashlights which might give away the officers’ position when confronting suspects or armed criminals.

2. Officer Safety

Thermal imagers are excellent in protecting law enforcement officers who are sometimes caught in an unknown situation which could compromise on their safety. Before rushing into any premise for arrest, the use of thermal imagers help officers to determine the safety or danger of the environment first.

A simple domestic disturbance or assault distress call could activate law enforcement officers to the scene where a thermal imager could identify potential danger inside or outside the premise before charging into the premise for an arrest.

3. Surveillance Activities

Many criminals today are tech savvy to be familiar with standard surveillance techniques to conceal their illegal business dealings. This includes using disable light-sensing technologies that would disable the functioning of binoculars and video cameras. But the thermal imager is not affected by bright lights or technologies that try to counter its dynamic features to function well. Hence, the thermal imager could include video facility to record surveillance activities clearly as evidence in a trial.

4. Hidden Compartments

Thermal imagers have no X-ray vision feature but detect radiated heat from surfaces to identify potentially hidden compartments. Experienced law enforcement officers could identify thermal irregularities in an environment that would give rise to caution and extra inspection.
It is easy to identify split fuel tanks or hollow body panels which could be stuffed with illegal substances to hoodwink authorities unless a thermal inspection is executed.

5. Accident Investigation

Thermal imaging is highly useful in traffic re-constructions especially on determining speed of impact at road accidents. Accident re-constructions through thermal imagers measure the warm marks left by the involved vehicles to determine the parties at fault.

Police officers are more successful in searching and finding missing persons using thermal imagers in jungles, forests, caves, lakes or abandoned buildings. The thermal imager is versatile over various types of terrain to help rescuers cover a substantial area of search for faster and more successful searches.

7. Disturbed Surfaces

Thermal imagers are excellent in detecting changes to any surface or material which absorbs and releases heat in a way that helps law enforcement officers investigate the condition appropriately.
Any altered material impacts its thermal signature which makes it easier for a thermal imager to make a clear or distinct identification. This could refer to drywalls repaired or repainted and recently overturned earth.

8. Marine Patrol

Thermal imagers are versatile even in fog, smoke or mist which is common in maritime patrols. The thermal imager is functional in surveillance or navigation of watercraft enforcement required in search and rescue operations.

9. Locating Evidence

Disposed weapons or substances like drugs could be detected through thermal imagers with a latent thermal image of the whereabouts. Crime investigators could use thermal imagers to scan any area for potential evidence efficiently.

10. Tactical Teams

Tactical teams of law enforcement are being formed and trained on using thermal imaging technology and its gadgets to be fruitful in other areas.

Prenatal Ultrasound Imaging Secret Techniques

Technology has advanced tremendoigisly over many fields and industries to give consumers a higher quality lifestyle especially in the medical arena. Progressive technologies in medicine and imaging have synergized dynamic medical tools such as prenatal ultrasound imaging that is beneficial to doctors and pregnancies.

Relevant Tool in Pregnancy Checks

Ultrasound imaging is known as a highly effective tool in pregnancies. Doctors or gynecologists use ultrasound scans on pregnancies frequently today to check on the fetus development at different trimesters. This facility has become an extremely vital diagnostic tool that has advanced obstetrics rapidly in the last era.
Today, almost all pregnant women undertake the prenatal ultrasound examination at some point of their pregnancy to check on their baby’s growth and even gender. The most common application of Ultrasound during pregnancy by the doctor is at the 16th week at the 2nd trimester of the pregnancy when the fetus is considered more stable to view its form and health. With the advanced technologies of today, ultrasound imaging on fetus in prenatal checks could be performed from the 2nd semester with no harm to both mother and child.
digital ultrasoundThe frequency of prenatal ultrasound imaging is increased if there is a possibility of mal-development in the fetus during the pregnancy. The doctor would use the ultrasound scan to monitor further developments of the fetus that would alert them to improper growth patterns to curb danger on the mother and child.
The ultrasound also provides an exciting opportunity to parents for a view of their baby developing in the womb before delivery. Parents are usually awed by the sight of their baby on the screen although it takes a bit of time to figure out the baby’s position and form in the womb due to the untrained eye and inexperience of parents unlike the doctor who is able to point out the faculties and form of the baby deftly.

Types of Ultrasound Imaging

A well structured health care center would be well equipped with various types of ultrasound imaging for the doctor to administer based on the pregnancy term or condition of the growing fetus.

•    Standard Ultrasound
•    Advanced Ultrasound
•    Doppler Ultrasound
•    Transvaginal Ultrasound
•    Fetal Echocardiography
•    3D Prenatal Ultrasound
•    4D Prenatal Ultrasound

The ultrasound examination is painless and short. It is usually administered in 15 to 20 minutes by the attending gynecologist to view the form of the baby. The expectant mother lies on her back with her exposed belly which would be scanned by the ultrasound transducer after some gel is placed. A full bladder is necessary to conduct the ultrasound examination effectively for a clearer image.
The ultrasound procedure works with the transducer passing inaudibly high frequency waves into that part of the body to be reflected at various strengths for displaying the anatomic features of the fetus in the womb.

Benefits of Parental Ultrasound Imaging

The varied benefits of ultrasound imaging make this tool very attractive to assist doctors in diagnosing the condition of the growing fetus in the womb. Its image is also used to determine the duration of the pregnancy as well as the baby’s due date.
prenatal ultrasound Another dynamic feature of the ultrasound image is to determine the expansion rate of the uterus for the pregnancy to ensure a normal healthy pregnancy. This prenatal checking tool is able to pinpoint specific issues that may be the cause of irregular uterus development.
The advance technology in ultrasound imaging tool is helpful in identifying the breathing, excretion, heartbeat and body movements of the growing baby to rule out abnormality in its development. This includes birth defects like missing limbs, misalignment of spine, heart or urinary tract malformations. Fetal echocardiography is commonly administered to check on which images the flow of blood through the chambers of the heart and other major blood vessels of the fetus helps in the detection of the heart irregularities.
Moreover, ultrasound imaging could check and measure the baby’s limbs and spinal column to confirm its growth and formation to rule out abnormality. The brain of the baby could also be viewed and diagnosed accurately to confirm a healthy development or otherwise.
Multiple pregnancies such as twins, triplets or more could be detected using ultrasound imaging.

CCD vs CMOS Imaging Sensors

There are 2 types of imaging sensors in the market for various applications. They are CCD sensors and CMOS sensors. These are light converting devices that give out electronic signals through the release of electrons via the photoelectric effect.
This special process allows an electron to break away from its atomic orbit upon the striking of a photon. Both the CCD and CMOS imaging sensors manipulate this phenomenon for their dynamic effect in applications.
The differences between CCD and CMOS lie in the capturing of image, type of sensor built and reading of electrons and signals.

Advantages and Disadvantages

Both of these imaging sensor types exhibit advance imaging technologies that bring about dynamic outcomes in their applications. There are distinct differences between CCD and CMOS imaging sensors with distinct advantages and disadvantages from each other depending on the type of application engaged.

1) Speed: CCD vs CMOS Imaging Sensors

CMOS imaging sensors are much faster than CCD imaging sensors when it comes to speed. CCD sensors adopt a slower process of shifting electrons from their photo site to the appropriate circuit portion for amplification before the signal could be read.
CMOS sensors take on the dynamic task of amplifying the signal immediately as it is read from the electron photo site. With this fast speed process through CMOS, very fast computers are designed to speed up many tedious operations in many industries.

2) Noise
ccd image sensorCMOS sensors tend to be more susceptible to noise than CCD sensors due to the different surface areas chosen for the different imaging sensor. CCD sensor surface area is fully dedicated to electron photo sites while CMOS sensor photo site has transistors which could be hit by photons. This wrong miss produces noise which could also be caused by the large number of transistors present in the CMOS sensor.
CMOS imaging sensorImproved versions of the CMOS sensor overcome this noise issue with the transistors re-positioned beneath the photo sites; this is known as the Back-side illuminated CMOS sensor. This re-positioning allows more photons to hit their mark more frequently for better outcomes.
On the other hand, CCD sensors could also be susceptible to noise if the sensor experiences increasing heat. If CCD sensors are not re-designed to tackle this sensor heat issue, newer CMOS sensors would be seen as better performers.

3) Power Consumption:
CCD sensors tend to usurp more power than CMOS sensors due to the style of reading every photo site. There is a shifting process activated in the reading of photo site which consumes high power particularly with larger sensors. On the other hand, less power is consumed by CMOS sensors to perform their task.

4) Cost
The price of CMOS sensors is lower than that of CCD sensors due to the easy manufacturing in established silicon manufacturing line. However, larger CMOS sensors may cost more to produce as there could be a higher possibility of contamination in the manufacturing process. Extra cost is incurred to ensure lower contamination for producing larger CMOS sensors.

5) Rolling Shutter Effect
CMOS sensors tend to be susceptible to the skewing of fast movements known as the rolling shutter effect. Such effect tends to cause the image to be blurred if the fast moving object is not captured accurately.
The rolling of the shutter and the fast movement of elements in the frame create this problem. There is no rolling shutter effect with CCD sensors as rolling shutters are not used.

6) Blooming Effect
Another issue with CCD sensors is the blooming effect where the image could be over-exposed. This is caused by an over-exposure of adjacent pixels which are stored close together that one impact could adversely affect connecting or adjacent components. However, newer versions of CCD sensors sport designs that include an overflow draining of blooming effect. CMOS sensors do not have blooming effects.

Conclusion:
There are distinct applications for both CCD sensors and CMOS sensors based on the advantages and disadvantages mentioned. However, the choice of a camera is not primarily dependent on the type of sensor it sports but other factors such as performance, outcome, programming, quality or cost.
Market reviews would help buyers determine which type of camera is better depending on the objective as there are always newer models using more advance technologies.

CCD and CMOS are both image sensors found in digital cameras. They’re what’s responsible for converting light into electronic signals
