Abstract
Studied methods for measuring the threshold sensitivity of pyroelectric receivers are make it possible to minimize hardware measurement errors. The possibility of measuring the threshold sensitivity of pyroelectric receivers using a compact measurement circuit with a single optical element - a limiting diaphragm - is experimentally confirmed. The measurement scheme is based on the use of a “camera obscura” type projection system. The proposed measurement scheme allows to minimize measurement errors due to the absence of optical elements that distort the energy and spectral characteristics of radiation, as well as the absence of signal distortion when radiation propagates in air due to the compactness of the measuring circuit.
