Abstract
Ambient light and temperature fluctuations are suppressed in an optical receiver system by feeding the output of a photodiode directly to one input of a differential amplifier and, via a low pass filter, to another input of the amplifier. Reductions in amplitude in an optical information signal are automatically compensated.
