Abstract :
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
