Non-Selective Magnetoelectric Thermal Radiation Receiver Based on Cadmium Antimonide

The ways of increasing the sensitivity of a non-selective thermal radiation receiver based on cadmium antimony using the phenomenon of electromagnetic induction are considered and investiga­ted. It has been shown that the application of ani­sotropic NdFeB anisotropic magnet increases the volt-watt sensitivity of the thermal radiation recei­ver by 30 %. When a more powerful magnet is used, an additional increase in sensitivity is observed, but not in proportion to the magnitude of the additio­nal magnetic induction. The dynamic range of the created thermal radiation receiver, which is from 10 to 200000 W/m-2, is investigated.
