Photoelectric receiving amplifier circuit with LM307

Photoelectric receiving amplifier is used to magnify photoelectric diode or light activated triode's output signals. When the light intensity of incident lightchanges, photodetector will produce corresponding voltage or current, and photoelectric receiving amplifier is used to amplify the photo-current changes, photoelectric receiving amplifier circuit with LM307 is the ideal device to realize the above role. If it adds offset voltage VB on light activated triode OS18, its output current in the illumination is Vo=IpR1. The photo-current Ip'sminimum is determined by LM307's input amplifier drift IB, Ip's maximum is determined by the maximum voltage output Vomax.
