    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.

    Abstract: The present application discloses an optical receiving device and an optical sensing device. The optical receiving device includes a lens assembly, a reflecting member, and a photosensitive member. The lens assembly includes at least one lens. The reflecting member is located on a transmission path of light passing through the lens assembly. The reflecting member has a reflecting surface. The reflecting surface is configured to reflect the light passing through the lens assembly. The photosensitive member has a photosensitive surface. The photosensitive surface is configured to receive light reflected by the reflecting surface. After passing through the lens assembly, a detecting echo light beam reflected back from a target object is reflected by the reflecting surface of the reflecting member, so that the light is transmitted to the photosensitive surface of the photosensitive member intensively.
