Title:
LASER RADAR TRANSCEIVING ASSEMBLY AND LASER RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/051043
Kind Code:
A1
Abstract:
An optical chip based laser radar transceiving assembly (300) and a laser radar device (10). The transceiving assembly (300) comprises: a rear-end assembly (310) comprising an integrated multi-path optical assembly (300n), each optical assembly (300n) comprising a first interface (315) configured to transmit a detection optical signal and a return optical signal by means of the multi-path optical assembly (300n); and a front-end assembly (330) coupled with the rear-end assembly (310) and configured to receive and transmit the detection optical signal transmitted by the rear-end assembly (310) and receive the return optical signal from a detection environment and transmit the return optical signal to the rear-end assembly (310), wherein the front-end assembly (330) can change the spatial distribution of the detection optical signal according to the requirements of the detection environment. In this way, the flexibility and compatibility of the laser radar device can be improved.
