ABSTRACT:
A light wave distance measuring apparatus includes a light-sending optical system and a light-receiving optical system, which are preferably arranged to be parallel to each other. Intensity-modulated light of the light-sending optical system is transformed into parallel rays of light and projected towards a target, reflected back towards the measuring apparatus and detected by the light-receiving optical system in order to calculate the distance of the target from a reference point.
