LASER RANGE FINDING SYSTEM

摘要

PURPOSE: A laser range finding system is provided to enhance reliability in range-finding work even at a long distance. CONSTITUTION: A continuous wave generator outputs continuous waves synchronized to an initial signal which drives a laser diode. A first delay device connected to the continuous wave generator generates a delay signal about the continuous wave generation. The output by the first delay device is returned to the continuous wave generator as an input. The continuous waves are continuously generated with the frequency determined by the delay time of the first delay device. [Reference numerals] (AA) LD driving pulse; (BB) CW output;
