Patent ID: 7057727

Claim:
Device for the pixel-by-pixel photoelectric measurement of a planar or flat measured object or object to be measured, comprising: illumination means for illuminating the measured object or object to be measured with at least one essentially parallel light bundle at an angle of incidence of essentially 45°+/−5°; a two-dimensional array of light converter elements for producing electric signals in response to light remitted by the measured object or object to be measured; a tele-centrical imaging optics for imaging each point of the measured object or object to be measured onto the light converter element array at essentially the same observation angle of essentially 0° and with the same aperture angle of essentially maximally 5°; imaging means for imaging the measured object or object to be measured onto the two-dimensional array of light converter elements; filters provided in the imaging light path for wavelength selective filtering of the measurement light impinging on the light converter elements; signal processing means for processing the electrical signals produced by the light converter elements and for converting them into corresponding digital raw measured data; and data processing means for processing of the raw measured data into image data representing the colours of the individual pixels of the measured object.
