Flying spot scanner with scan detection |
| abstract |
A flying spot scanning system is provided by utilizing reflected light from a multifaceted rotating polygon which is then directed to the scanned medium. A light source illuminates given facets of the polygon to provide the desired function of spot scanning. In each scanning cycle, information is transmitted to the scanned medium by modulating the light from the light source in accordance with a video signal. To assure an effective sequence of spot scans and the resulting scanning cycle, a beam splitter is employed to provide an unmodulated light beam from the original light beam which is directed at the illuminated facets of the polygon at an angle of incidence different from that of the incident modulated beam. An optically sensitive detector is aligned in relation to the scan width of the scanned medium so as to receive only the unmodulated beam during each scan cycle to determine the start/stop of each scan. |
