WebA photodetector salvaged from a CD-ROM drive. The photodetector contains three photodiodes, visible in the photo (in center). Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation. [1] There is a wide variety of photodetectors which may be classified by mechanism of detection, such as … WebA laser sensor uses a “laser” to emit light in a straight line. Its visible beam spot makes alignment and positioning very easy. Since the light beam is focused, the sensor can be installed without worries about stray light. The major types of laser sensors include reflective, thrubeam, and retro-reflective.
