OPTICAL SENSOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18311273 titled 'OPTICAL SENSOR

Simplified Explanation

The patent application describes an optical sensor that can detect a sensing object.

  • The sensor includes a plate-shaped substrate with a front surface, back surface, and a hole that goes through both surfaces.
  • A light-emitting element is attached to the substrate and emits light.
  • A first light-receptive element is fixed to the back surface of the substrate and receives reflected light from the sensing object.
  • The first hole extends from where the first light-receptive element is fixed towards where the light-emitting element is fixed.


Original Abstract Submitted

An optical sensor configured to detect a sensing object includes a plate-shaped substrate, a light-emitting element, and a first light-receptive element. The plate-shaped substrate has a front surface, a back surface and a first hole piercing through the front surface and the back surface. The light-emitting element emits light and is fixed to the substrate. The first light-receptive element receives reflected light emitted from the light-emitting element, reflected off the sensing object and traveling into the first hole. The first light-receptive element is fixed to the back surface of the substrate. The first hole extends from a position at which the first light-receptive element is fixed toward a position at which the light-emitting element is fixed.
