Document Type and Number:
WIPO Patent Application WO/2022/217948
Kind Code:
A1
Abstract:
A receiving device (1002) and a laser radar. The receiving device (1002) comprises: a circuit board (100); a plurality of receiving units (101) located on the circuit board (100) and configured to convert optical signals into electrical signals; a packaging sidewall (102) protruding from the circuit board (100) and arranged around the plurality of receiving units (101) to form a cavity (103) accommodating the receiving unit (101); and a packaging layer (104) located on the packaging sidewall (102) and covering the cavity (103). The laser radar comprises: a transmitting device (1001) configured to provide a transmitted beam (L); and a receiving device (1002) configured to detect an echo beam (L') formed after the transmitted beam (L) passes through a target object (1003). The installation difficulty of the receiving device (1002) is reduced, and the installation speed of the receiving device (1002) is improved, thereby improving the installation efficiency.
