Abstract

PURPOSE:To measure the distance up to an object at high accuracy from the relation between the amplitude change of the combined receiving signal light obtaininable by sweeping of modulating frequency and the modulation frequency by receiving the combined signal of the refrected signal lightof the object and part of transmission signal light with a reflecting mirror.
