Abstract
A method and a device for the optical distance measurement or for the optical detection of objects with an at least partially specular reflective surface (12) are based on the fact, that light through the specular reflective surface (12) and a diffuse scattering at a reflector (4) is directed to light receiving means and detected there.

Method for the optical distance measurement or for the optical detection of objects with an at least partially reflective surface (12), wherein through the reflective surface (12) and a diffuse scattering on a reflector (4) light is directed to light receiving means and detected there.
Device for the optical distance measurement or for the optical detection of objects with an at least partially reflective surface (12), comprising a light source (2) for the generation of a light beam (11), light receiving means and evaluation means for the evaluation of light signals received through the light receiving means, characterised by an at least partially diffusely scattering reflector (4), wherein light is capable of being directed from the light source (2) through the reflector (4) and the surface (12) to the light receiving means.
