ABSTRACT:
An object is scanned first with a flying light spot from a variable-intensity light-spot projector, and the reflected light is used as signals to point by point modify the output of the projector in accordance with the intensity of the respective reflective-light signal. Thereupon the object is scanned a second time and the projector instructed to apply less light than before to those points of the object from which a strong reflected-light signal was received during the first scan, and to apply more light to points from which a weak reflected-light signal was received during the first scan.
