ABSTRACT:
An apparatus for detecting the displacement information of an object to be measured has a light source, an electro-optical crystal disposed at the incidence position of a light beam from the light source, the light beam being modulated in the electro-optical crystal, the light beam being internally reflected at least once in the electro-optical crystal and emerging therefrom, and a light receiving element for receiving the light from the object to be measured to which the light beam having emerged from the electro-optical crystal is applied, the displacement information of the object to be measured being detected by the light reception of the light receiving element.
