Abstract

A double spectral image sensing device has been developed for industrial tasks. The device comprises a common objective shared by two bidimensional CCD detectors that see the same field of view by means of a 50-50 beamsplitter and a mirror. Proper adjustment of the optics and of both detectors, one with respect to the other, yields two almost identical images at the output of the detectors. If limited bandwidth interference filters are inserted in front of each detector, many useful applications arise, such as robot welding vision, pyrometry in the range 820°C to 1350°C, and surface inspection.
