Method and system for area-wise characterisation and quality control of at least partially optically translucent and internally optically scattering products

摘要

a product in the surficial zone at least partial optical translucency and light scattering inside the zone such as ceramics particles pressed or sintered products, organic materials are nondestructively, without contact and bildgebend on locomotive the physical properties and qualities were studied.by a fine lichtmuster on fixed or moving surface, which is covered with a projektionsbild imaging systems and the local sharpness, which the material and surface properties is modulated, is determined.by the use of different wavelengths and projektionsmuster many shallow defects and characteristic material properties compared to reference values in the production line with simple means to be examined.
