Infrared Cameras are also known as thermographic cameras. They are a valuable innovation in the field of photography. These devices provide high-quality thermal imaging solutions on the basis of infrared radiation. These images are required in fields like astronomy and healthcare.
History of thermographic technology
Infrared cameras were first used during the Korean War. The reason behind this was that they were extremely useful while fighting in the dark. These cameras work on the basis of heat detection and thus they would be used to identify the position of soldiers when they fought during the night. In those days, these devices were manufactured just for the armed forces.
While equipment based on thermal imaging is still extensively used for military operations, with changing times infrared imaging is used in various fields like astronomy, medicine, bio-conservation, archaeology, flame detection, and firefighting.
Thermographic equipment is used in wide range of medical procedures such as oncology, breast thermography, and fever screening. FDA 510k Cleared Medical Infrared Cameras, FDA 510k Medical Device Clearance are some of the medical imaging devices used for acquiring high-quality imaging solutions. These electronic devices are extra sensitive and are used in the airports for detection of H1N1 viruses.
Often these cameras are used by scientists or forest guards to keep track of animals in the dark.
Types of thermographic cameras
There are two types of thermographic gadgets: cooled or uncooled. The cooled detectors come in vacuum sealed cases. This is because the semiconductor materials like lead salenide, indium antimonide, and mercury cadmium telluride need to be cooled to extremely low temperatures in order to get proper images.
The uncooled imaging devices operate in normal temperatures. Pyroelectric and ferroelectric materials are used in this type of imaging equipment. They do not need any type of cooling therefore do not have vacuum sealed cases. This variety is more expensive than the cooled ones.
The following parameters are to be kept in mind while purchasing or using these devices:
Range
Number of pixels
Sensor lifetime
Minimum resolvable temperature difference (MRTD)
Input power
Field of view
Noise Equivalent Temperature Difference (NETD)
If you want to have a unique experience in photography, buy an infrared camera to get a magical experience of thermal imaging. These are one of the most sought after cameras in present times and may be ordered through the websites of the manufacturers.
