Abstract
An arrangement for optically measuring the surface, such as surface shape and/or associated surface defects, of an optionally glossy target object, comprising: a diffusive, semi-transparent illumination structure defining a hollow, preferably curved, elongated surface shape, constituting a tunnel shape, configured to surround at least one target object at least partially, a number of LED (light-emitting diode) light sources optically coupled to the illumination structure for illuminating at least one target object via the surface of the illumination structure, wherein the light sources are situated at a distance from the surface of the illumination structure, wherein the LED light sources are arranged in a matrix array along the curvilinear cross-section of the illumination structure and along the length of the tunnel shape of the illumination structure, at least one imaging device, configured to image the target object.
