发明名称 DISTANCE MEASURING APPARATUS USING PULSE LIGHT
摘要 The present invention relates to a distance measuring apparatus and method having a structure enabling highly accurate distance measurement. In particular, the distance measuring apparatus according to the present invention comprises at least a measurement system for detecting, of measurement pulse light emitted into a measurement optical path toward a target, information concerning a reflected beam from the target. In order to prevent undesirable reflected beams, which form erroneous information, among reflected beams of the measurement pulse light from being received, an operation for detecting reflected beams of the measurement pulse light is inhibited for a predetermined period of time from the emitting time at which the measurement pulse light is emitted.
