Abstract

PURPOSE:To pick up ripple components without causing the shift of phase for required signals, by rejecting the ripple component only out of output signals of a photodetector through the use of inverting circuit and addition circuit. CONSTITUTION:The ripple and signal are both smoothed with a capacitor Ct for the waveform of an output signal of a photodetector, and the result inputs to an inverting input of an operational amplifier OP1 and outputted from the output side through inversion, and the output signal is added to a signal through a resistor Rt2 and a signal through a resistor Rc and Zener diode ZD1, ZD2. This signal is inputted to an inverting input of an operaional amplifier OP2 through a resistor R3 and inverted and this inverting signal is added with a signal through a resistor R4. Further, this signal is inputted to an inverting input of an operational amplifier OP3, and the output signal is added with a signal from a resistor R7 and picked up. The signal thus picked up has no ripple with smoothing, and the signal component can be picked up without causing the phase shift.
