LASER TRANSCEIVER MODULE, LASER RADAR AND WINDOW FOR LASER RADAR

摘要

Disclosed are a laser transceiver module, a laser radar (100) and a window for the laser radar. The laser transceiver module comprises a transmitting module (11) and at least two receiving modules (12), wherein the at least two receiving modules (12) are arranged at the periphery of the transmitting module (11), and fields of view of the receiving modules (12) are spliced together to obtain a receiving field of view of the laser transceiver module, such that the size of the laser radar (100) is reduced, a short-distance blind area of the laser radar (100) is reduced, and the receiving modules (12) are arrayed and modularized easily. The laser radar (100) comprises a main case (1) having a front space in which the laser transceiver module is housed and a rear space in which a circuit board is disposed, a rear case (2), and a front window (3) having a curved surface shape protruding forwards, wherein the front window (3) is divided into an emission mask (34), through which laser light in the circumferential center can pass, and a reception mask (33), through which laser light at the periphery of the emission mask (34) can pass, and the laser radar (100) has the advantages of integration, miniaturization, a large field of view, etc.
