Lichtmessanordnung zur Detektion von Oberflaechendefekten

The invention relates to a light measuring setup for the detection of surface defects (scratches, scores, spot defects, etc. The light measurement setup consists of a laser source (6), a rotating sample support (2) to receive the object under test (10) and a drive motor (3) and a sensor unit (1) comprising two receivers, whereby one receiver is designed as a multiple ring detector (4) to detect radial light distribution and the second receiver is designed as an annular array (5) to detect azimuth distribution.
