Abstract

PURPOSE:To stabilize the output of the optical signal through a simple constitution by detecting the optical modulation signal to be converted into the electric signal and then isolating the horizontal synchronous signal to be fed back to the luminous element driving circuit in order to keep the amplitude constant for the signal component.
