光波距離計。[Claims for Utility Model Registration] An optical path switching member selects between an external optical path in which intensity-modulated light from a light source reaches a light-receiving element via a target object, and an internal optical path in which the intensity-modulated light from a light source reaches a light-receiving element without passing through a target object. , a light wave distance for determining the distance to the target based on a phase difference between a first signal obtained from the light receiving element through the external optical path and a second signal obtained from the light receiving element through the internal optical path; In the meter, one of the external optical path and the internal optical path has an outer periphery,
Transparent portions are provided on the outer periphery and the inner periphery of the disk, the other of which has an inner periphery passing through, at equal angular pitches, and so that the external optical path and the internal optical path are selectively selected. and a light shielding part are arranged alternately, and the density of the light transmitting part on at least one of the outer periphery and the inner periphery is sequentially changed in the rotation direction to configure the optical path switching member. Total.
