“Received light” recognition type laser sensor detect the light from a transmitting element to a receiving element. Three different types - Reflective model, Thrubeam model, and Retroreflective model are explained here.
How Does Beamforming Work? How does beamforming form the shape of a beam? Signal beams are similar to light beams. The shape of a light beam produced by a flashlight is fixed. If another flashlight produces a light beam in the same direction, the two light beams are superimposed, thereby...

irregularities create roughness. This does not break the law of reflection. Each ray reflects back at the same angle at which it struck the object but in a different direction. So diffuse light is scattered light. This scattering is what causes the diffusion and softness of the light beam. ...
