Abstract : An optical scanning system having a rotatably driven, curved reflective surface with a predetermined pattern of reflective and non-reflective portions annularly arranged near the circumference of the surface. The emission source, such as an infrared source, is focused onto an area of the surface in the ring of the portions such that when the surface is rotated the portions are rotated under the image and as each reflective portion is brought into alignment with the image, the image is reflected to a detector. The orientation of the surface is continuously monitored for correlation with each detection. The sum of the orientations at detection per rotation defines placement of the source in the field of view of the system. Appropriate computer programs may be used to increase processing speed and, thereby, increase efficiency. (Author)
