Question

What are the two frequency ranges used in INFRARED cameras( Thermal cameras)? What are the differences between these two frequencies?

Answer 1

Infrared camera is cesed for thermal Imaging of any object. sull eyes are detectors which are designed to detect visible light waves. There are formy of light Car radiation) which we cannot rec. Actually we can only see a very small part of tire range of radiation called the tromagnetic spectrum.

Infrared cameras are sensitive to wavelagby from about 1,000 nm (tum) to about 14,600mm (14um). The frequency ranges of Infrared water are from 4x104 Hz to 10 20 Hz.

The Infrared Camere is working between the above tuco prequency renges of the IR wave length. If the prequrey is higher wave length is o increasing which makes the IR camera more senstine to the thermal Imageing. ernal imageing or IR camers wild through the IR-rediation wake off on the object and it will detect the parts which are more hotter or less hotter. parts which are more hotter will labbears Red blue in colour and as temprature es decrease are or or cooler cooler it will it will ab appears to be Blue in colour.
