Abstract

PURPOSE: To improve the SN 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 supply.
CONSTITUTION: The load is conndcted to the AC power supply via the full wave rectifying circuit 181 and switchlng circuit 171. DC power is fed to the projector 101 from another AC power supply via the diode 102, and the charge in the capacitor 110 illuminates the light emitting diode 108 with turning on of the thyrestor 106. This light is received with the photo detection diode 162 of the photo detection unit 151 to turn on the transistors 166 and 169 of the amplifying circuit 161 and to turn on the thyrestor 178 of the switching circuit 171.
