摘要

在外差模式下使用时,普通的红外探测器可能受到热产生或放大器噪声的支配,可以作为几乎理论上完美的接收器。将光敏电阻器与具有相同电面积的光浸式光电磁探测器进行了比较。

Measurement of performances of uncooled HgCdTe photodetectors in heterodyne regime of operation
An ordinary infrared detector that may be dominated by thermal generation or amplifier noise can serve as nearly theoretically perfect receiver when used in a heterodyne mode. A photoresistor has been compared with an optical immersed photoelectromagnetic detector with the same electrical area.
