Not all area of the light spectrum can be seen by human eyes. As a modern technology, infrared detectors are widely used to pick up some of the area that we can’t see with naked eyes. Infrared detectors are now used in many fields, for example, they have been successfully applied in construction, public service and science.
Large detecting area is one of the advantages for infrared detectors. Infrared detectors can be used to detect an area and pick up the infrared spectrum.
For that infrared detectors can work in real time, they are quite suitable of picking up movement. For example, firefighters can use infrared detectors to see objects or people through heavy smoke.
Infrared detectors can also be utilized to construct large structures, such as skyscrapers. Then can detect leaks in pipes if there are, which are difficult to see in other ways.
The detection of infrared detectors is on the basics of the differences in object temperature. As a result, it is difficult for the detectors to identify the difference between two objects with the similar temperature range, which may bring about inaccuracies in some situations.
The price of infrared detectors is still quite high for their further application in many fields.
