| 摘要 |
An opto-electronic device that includes a source of a collimated beam of light, a reflector, and at least on partly reflective surface. The partly reflective surface may be a surface of a detector, or alternatively a surface of a partly reflective material behind which one or more detectors are positioned. The partial reflectivity of the surface is exploited to reflect the light beam several times to the same detector, or alternatively among several detectors. Illustrative applications of the device include a pulse sharpener, a touch screen, a serial-to-parallel converter and an opto-electronic switch.
