Abstract
The measuring device comprises a lighting system, a photoelectric receiver unit and optical means. The lighting system applies light to image elements disposed in strip-shaped lighting regions () at a standardized angle of incidence range. The photoelectric receiver unit comprises several photoelectric line sensors () disposed parallel at a distance apart which are sensitized to different wavelength ranges by color filters () connected upstream. The optical means comprise linear optical arrays () which pick up the measurement light reflected by the image elements at a standardized range of angle of reflection and direct it to one of the respective line sensors (). By means of optical screening and other structural features, cross-talk effects between adjacent image elements are largely reduced.
