測距装置。 A light source that is intensity-modulated at a constant frequency, a first receiver that receives the light that is spatially propagated from the light source and reflected by a reflective mirror of the object to be measured, and a first receiver that directly receives a portion of the light from the light source. The phase of the amplitude modulated wave detected by the second optical receiver and the first optical receiver is compared with the reference phase of the amplitude modulated wave detected by the second optical receiver, and the phase difference is measured. An optical distance measuring device comprising: a measuring means for determining the distance to an object.
