Abstract
The invention concerns a device for characterization of subjective speckle formation, especially for quantification of the speckle contrast. The device has a projection surface () and a coherent or partly coherent light source () for projecting of an image onto the projection surface (), a detection unit () for generating of speckle images () of the image projected onto the projection surface (), as well as a data acquisition and analysis unit () for processing and evaluation of image data.
