Abstract
The invention relates to a method and an apparatus for examining an object, particularly in terms of the surface morphology thereof. Said apparatus comprises a transportable housing which can be placed, especially by hand, above the surface segment of the object that is to be examined, and at least three light sources, the optical beam axes of which extend at a slanted angle of incidence relative to the surface segment that is to be examined. The light sources are disposed inside the housing and can illuminate the surface segment that is to be examined through an illumination aperture in the housing. The apparatus further comprises at least one light sensor for detecting the light reflected on the surface segment that is to be examined and a control and evaluation unit which is connected to the light sources and the light sensor. The light sources are arranged such that the optical beam axes thereof extend on different, non-parallel reference planes.
