Title:
LASER RADAR SYSTEM AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/051579
Kind Code:
A1
Abstract:
A laser radar system and a vehicle. The system comprises: transceiver modules (M1); scanning modules (M2); and a processing module (M3) comprising an optical processing device (M31) and a signal processing device (M32); the optical processing device (M31) comprises an optical amplifier (M311) and a light splitting module (M312); the transceiver modules (M1) comprise first transceiver modules (M1a), each comprising a distribution device (M11), a receiving device (M12), and a laser (M13); the optical amplifier (M311) amplifies laser light, and the light splitting module (M312) divides the amplified laser light into multiple beams and then sends same back to the distribution device (M11) of the transceiver module (M1) that previously sent the laser light; the distribution device (M11) processes the laser light to form a detection beam and reference information, sends the detection beam to the scanning module (M2), and sends the reference information to the receiving device (M12); the scanning module (M2) scans an object according to the detection beam, receives an echo beam reflected by the object, and sends the echo beam to the receiving device (M12); the receiving device (M12) forms an electrical signal according to the echo beam and the reference information and sends the electrical signal to the signal processing device (M32) for analysis. The components are modularized and spatially decoupled, each laser (M13) can use different codes to prevent crosstalk, and the optical amplifier (M311) can be shared to amplify signals.
