OPTICAL PULSE GENERATOR

摘要

PURPOSE:To prevent output pulse width from being varied or lost by arranging light transmitting windows for generating original pulses and the ones for generating control pulses in parallel on a light shielding plate. CONSTITUTION:Light shielding windows 5 for an upper optical head and light penetrating windows 5' for a lower optical head are set up on a light shielding transmitting plate 4. Outputs from the upper optical head are original pulses and outputs from the lower optical head are used for controlling the original ones. If the amplitude of output pulses from the upper head is controlled by the voltage obtained from the average value of the amplitude of output pulses from the lower head, output pulses with constant amplitude can be obtained.
