Abstract
Apparatus for measuring the distance to an object comprising projection means for projecting a radiation beam onto the object including a radiation generating means and a first optical system, and detection means for detecting the radiation beam reflected from the object including radiation detecting means having a radiation-receiving surface for detecting the intensity distribution of the radiation on said radiation-receiving surface and a second optical system for guiding at least a portion of the reflected radiation beam from the object to said radiation-receiving surface, an optically conjugated relation being held between said radiation-receiving surface and an area of the optical axis of the first optical system.
