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.
