ABSTRACT:
A method for optically measuring a surface is described, in particular, for a surface having a spherical form and a high reflection of radiation. The surface is illuminated by at least one radiation source, as well as by at least one structured light source, in order to produce an illumination structure on the surface to be measured, and to then record the illumination structure using a camera; prior to measuring the surface, a coating being applied thereto in order to reduce the reflected radiation, the electrostatic coating principle being followed when applying the coating to the spherical surface. Thus, a method for optically measuring a surface is described, which provides for a coating to be uniformly deposited on the entire surface of the test object and to have a thickness of less than 0.01 mm.
