Photodetector The Thermistor and Barretter are the examples of the commonly used resistive element. Many hydrocarbons absorb IR at approximately 3.4 micrometers and in this region H2O and CO2 are relatively transparent. Bolometer In a microwave power measurement using bolometer, the principle of working is variation of inductance with absorption of power resistance with absorption of power capacitance with absorption of power cavity dimension with heat generated by power. These are available in different spectral ranges. Thermopile detectors do not depend on wavelength to work. Thermal detectors, explained by RP Photonics Encyclopedia; … The two main types of thermal detectors are: Thermopile detectors; Bolometer detectors; Thermopile thermal detectors. I explained to him how the bolometer could be improved.
