Abstract: The present disclosure relates to light detection and ranging (LiDAR) systems, such as LiDAR sensors detecting objects with various reflectivities at various distances. An optical detection system includes a transmitter for emitting at least one beam of optical radiation, a receiver including an imaging processor and an anamorph prism system, and at least one scanner for guiding the at least one beam along a scan direction across a target scene and/or guiding a reflected optical radiation of the at least one beam from the target scene to the receiver. The anamorph prism system is configured to produce a processed beam by compressing the reflected optical radiation in a predefined direction by a predefined factor. The imaging processor includes a two-dimensional detector and is configured to generate an image based on the processed beam on the two-dimensional detector, the image having an aspect ratio that is based on the predefined factor.

Abstract: A laser emitting apparatus includes a light beam generation apparatus and an optical assembly. The light beam generation apparatus is configured to generate a first light beam and a second light beam, where the first light beam is incident to the optical assembly and is emitted from the optical assembly, the second light beam is incident to the optical assembly and is emitted from the optical assembly, and a first spot formed by the first light beam in space and a second spot formed by the second light beam in space are separated in a horizontal direction.
