Thermal rediation detector (TRD)‎ modeling

الملخص EN

This paper describes the theoretical principles of TRD operation based on thermal absorption of incident power of radiation.

In the modeling procedures, the main parameters influencing on the detector features have been introduced.

So the this model allow us to predict the behavior of different types of thermal detectors.

It is found that the temperature response of the detector against the frequency of incident radiation in logarithmic scale describes the TRD as a typical low pass filter characteristics.

The cut off corner frequency is found to be at 1 Hz under which the temperature change attains a saturation value.

In the sense that the thermal detector will detect all the incoming radiations of higher frequency.
