Abstract
A range-finding system for measuring a target distance from a point of measurement to a target object, comprising a slave unit for calculating and indicating the target distance based on a waiting time from transmission of an interrogation signal to reception of a response signal and a master unit placed at a certain correction distance from the target object for transmitting the response signal when a delay time corresponding to the correction distance has elapsed from reception of the interrogation signal.
