The Hamamatsu Photonics light modulation photo ICs were developed for optical synchronous detection under disturbance background light. A photodiode, preamplifier, comparator, oscillator, LED driver and signal processing circuit, etc. are all integrated on a monolithic photo IC chip. Optical synchronous type photo reflectors and photo interrupters, which less susceptible to disturbance background light, can be easily configured by just connecting an external LED to this photo IC.
