Abstract
The present application discloses an optical receiving device, including: a receiving sensor; an optical assembly arranged on a side where a photosensitive surface of the receiving sensor is located. The optical assembly includes a first prism having a first end surface, a second end surface, and a plurality of sides connected between the first end surface and the second end surface. The plurality of sides include a first side and a second side. At least a portion of laser signals reflected by a detecting target is refracted by the first side and enter the first prism. At least a portion of laser signals refracted by the first side is refracted by the second side and emitted from the first prism to reach the receiving sensor.
