Thermal Imaging Camera As The Technological Hand In Fire Rescuing Campaigns
A thermo graphic camera is the one that translates thermal or heat energy into visible light to appraise an object or any specific scene
. The image formed by the thermo gram and analyzation is known as the thermograph process. TIC"s are basically digital cameras which are much more advanced and are more useful.
All entities including living beings radiate thermal energy from their outer surface. A Thermal imaging camera converts the infrared energy produced by the bodies into a visible light which can be seen by the colors produced on the screen. The shades of red, yellow and orange depicts the hotter areas and colors like blue, green and purple represents colder areas depicting moisture.
These cameras are advanced equipments which are highly sensitive and are highly priced. They consist of five components namely optic system, detector, amplifier, signal processing and display. All these parts work together to represent infrared radiation which are given off by warm objects or flames in case of fire. They are light weight and have a high resolution thermal detector. The accuracy of a thermal imaging camera ranges between 2 "" 5 %.
The TIC"s were mainly used as firefighting equipment. They allow seeing the areas of heat through smoke, darkness or any other porous barriers. They are best for searching trapped people where rescuers cannot see them. It picks up the body heat and helps the firefighters to locate them. Sometimes they use mini-recorders with it to record sensitive noises which cannot be heard by them.
These days thermal imaging camera is being used in many other fields also. Pest control experts use them to identify the influx of pests in an enclosed area. It displays the difference in temperature of the area. Plumbing professionals use TIC to locate blockages in pipes from outside. They are used regarding various military and surveillance issues. Law enforcement agencies use mini- recorders and thermal imaging cameras to find hidden suspects. The paranormal investigators also use mini- recorders and TIC"s to observe the change in surroundings.
These cameras are being used in the field of medicine as sensitive diagnostic tools. They are used for non invasive techniques which do not require radiation or any other therapy. They can be used to study skin temperatures in humans or even animals. TIC"s assists the medical professionals in areas related to neuro surgery, cardiovascular and even in melanoma that is finding tumor. With advanced technology the cameras are being used in many fields of research also.
