Title:
RADAR SYSTEM, PHOTODETECTOR, AUTOMOBILE, AND PHOTODETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/237557
Kind Code:
A1
Abstract:
A radar system, a photodetector, an automobile, and a photodetection method, used for performing photodetection of multiple angles. The radar system (300) comprises a laser module (310) and a photodetector (320), the photodetector (320) comprising a first polarising scanner (321) and a photoreceptor (322). When the laser module (310) emits a detection laser, as the refractive index of the first polarising scanner (321) can change, the first polarising scanner (321) detects the echo signal of the laser by means of refraction of different refractive indices, such that the photoreceptor (322) senses echo signals of different angles, thereby increasing the field of view angle of the radar system, and reducing the cost of the photoreceptor compared to the solution of increasing the photosensitive area of a photosensitive chip in the photoreceptor (322).
