Abstract

PURPOSE: To improve the S/N ratio with increased peak value of optical pulse, by flowing the drive current of light emitting diode once at a half period with specific phase of AC power input.
CONSTITUTION: The load 3 is connected to the AC power input 4 via the full wave rectifying circuit 13 and the switching element 12. The projector 1 is connected to the full wave rectifying circuit 13 to receive DC power. The operation of thyristor 21 ON-charging of capacitor 23-thyristor 22 ON-light emission of light emitting diode 6-thyristor 21 OFF is produced once at a half period. The light emission of the light emitting diode 6 is received with the photo detection diode 7 of the photo detection unit 2 to turn on the transistors 51, 52 of the amplifier 8 and trigger circuit 10 and the switching element 12.
