Thermal imaging technology evolved in Britain to support the military
activities especially for anti-aircraft activities. Thermal imaging can provide
valuable information that is practically impossible to capture with any other
tool in real time . One of its application thermal scanner which can identify
the presence of people affected with fever during corona or H1N1 outbreak can
reduce risk moreover the time for
identifying the threats. So in this article we will share the working and
recent trends in thermal imaging
technology .
Thermal imaging is a technique of using heat given off by an
object to produce an image of it or to locate it . This images are taken with the help of a infrared camera. Then
it is processed with the help of thermal imaging software with an advanced algorithm.

Infrared
energy coming from an object is focused by the optics onto an infrared detector.
The detector sends the information to sensor electronics for image processing.
Inside the thermal camera, there are a
bunch of tiny measuring devices that capture infrared radiation, called micro
bolometers, and each pixel has one. From there, the micro bolometer records the
temperature and then assigns that pixel to an appropriate color. Which allows
temperature values to be read from the image. In order to do this, complex
algorithms are incorporated into the thermal imaging camera.

Thermal imaging technology widely used in building
diagnostics. It is easy to scan an entire building to detect problems associated with ventilation,
water proofing ,electrical heating and
energy losses. In the area of security &
surveillance Indian forces also using this technology to locate the
infiltration across borders. Indian airforce detected the terrorists attacked
Indian airbase at Pathankot by using thermal imaging camera. Indian Armed Forces operate Israeli built Heron and Searcher
Unmanned Aerial Vehicles (UAVs) both of which are fitted with extremely
sensitive thermal imaging devices which can pick up the movement of
infiltrators based on heat signatures that their bodies generate.
In recent years
thermal imaging play a major role in mass screening , In areas such as airports
to monitor the potential spread of virus like H1N1, Corona by identifying fever
symptoms especially human body temperature . Over all it is a promising
technological invention that can be used to measure or observe subjects in
areas hazardous or inaccessible.
