Technical Examples
  1. A light receiver apparatus for a vehicle comprises a photo diode for receiving an incident light form a surrounding environment, a FET connected in series with the photo diode and a filter for extracting an a.c. signal from a received light signal developed at a junction with the photo diode when a reverse-bias voltage is applied to the photo diode. The a.c. signal is produced by removing from the received light signal a signal corresponding to a background light in the incident light. The FET varies a resistance thereof in accordance with the received light signal so that a d.c. signal in the received light signal is regulated to a fixed level irrespective of the intensity of the background light in the received light.
