Inspektion von farbigen Oberflaechen

The method involves using a sensor (30) extending in two directions (x,y). An essentially continuous fanning out or splitting (20) of incident light from a small image region or object region is produced, especially on several adjacent first light-sensitive elements (31) of the sensor. At least one simultaneous, also essentially continuous, spectral fanning out of the incident from another (small) image region or object region is produced, especially on several more adjacent light-sensitive elements of the same sensor. ADVANTAGE - Facilitates spectroscopic measuring of colour and attains real time requirements for industrial inspection. Determines all relevant spectral parts of image points for colour inspection using high camera speeds
