Pulse thermal load for thermoelectric detector calibration

Experimental technique and devices

The work is devoted to the calibration of the developed thermoelectric detectors with different sensitive elements. A pulsed laser diode with a power of 5 W was used as a radiation source. A lamp with a tungsten filament was also  used to set the combined thermal load and assess the overall level of sensor sensitivity. The performed calibration procedures made it possible to obtain volt-watt characteristics for thermoelectric detectors of a new type, which will  help to better describe the thermal processes of high-intensity shock-wave interactions occurring in a pulsed gas-dynamic experiment.
