Optical sensor having light projecting prism |
摘要 |
An optical sensor projects light rays emanating from a light emitting element that are collimated by a lens and reflected by a mirror and then directed to a light projecting prism. The collimated light rays incident upon the prism are refracted at an incident surface and come out from the prism through a light exit surface so as thereby to be projected into the field of detection. Light rays passing through the field of detection are directed to a light receiving prism. The light rays incident upon the light receiving prism through a light incident surface are reflected by a light exit surface and then come out from the light receiving prism. The outgoing light rays are received and converted into an electric signal by a light receiving element.
