Abstract: Apparatus for optically sorting small light objects such as beans and/or grains on the basis of size and color. A feeding mechanism separates the objects one from another and delivers them in a free falling condition to an optical analysis means where each object is uniformly illuminated. The analysis is based on the amount and spectrum of reflected light which is conveyed to a pair of light transducers having different response characteristics. The electrical signals developed by the transducers are simultaneously analyzed for absolute values to determine object size and relative value of the integrated signals to determine object coloring.An annular analysis head is employed with the objects being analyzed falling through the central opening. The head is comprised of a pair of annular rings with a predetermined gap between the rings located at the central opening. Plural fiber light conducting rods are uniformly spaced about the circumference of the gap so as to collect light reflected from the object.
