When a 1lx peak value light signal isinputted in the photoelectric cell,then the signalgo through bipolar amplifier,will output 400mV peak value;the detector sensitivity at 4KHZ is lower 3dB than at 1KHZ;when using F:2 calibration ten or parabola reflector on the infrared signal source and detector,the detect distant can be 30.48m(100 feet).This circuit can be used in high secrecy communication system.
