Abstract: Example radar systems, optical detectors, vehicles, and optical detection methods are provided. An example radar system includes a laser device and an optical detector. The optical detector can include a first polarization scanner and a photosensitive device. The laser device can be configured to emit detection laser. The first polarization scanner can be configured to refract an echo signal of the detection laser, where a refractive index of the first polarization scanner is variable. The photosensitive device can be configured to sense the echo signal refracted by the first polarization scanner.

Abstract: A distance measurement system and a vehicle are provided. The distance measurement system includes a scanning module and a distance measurement module. The distance measurement module is configured to: emit laser light to the scanning module, and receive reflected light transmitted by the scanning module. The scanning module includes a moving component and a lens group. The moving component is configured to drive the lens group to perform scanning. The lens group is further configured to: receive reflected light of a measured object in an environment of the distance measurement system, and transmit the reflected light to the distance measurement module.
