Abstract
(EN) The invention relates to the technical field of laser radars, in particular to a laser emission device and a laser radar. The laser emission device comprises a laser emission array (110), a first laser emission unit group (120) and a first emission optical adjustment unit group (140); the laser emission array (110) comprises a first laser emission unit group (120); the first laser emission unit group (120) comprises a plurality of first laser emission units (122); the first emission optical adjustment unit group (140) comprises a plurality of first emission optical adjustment units (142); a first emission optical adjustment unit (142) in the first emission optical adjustment unit group (140) is arranged corresponding to a first laser emission unit (122) in the first laser emission unit group (120), and is used for adjusting the emitting direction of a laser signal emitted by the first laser emission unit (122) in the first laser emission unit group (120); a laser beam emitted by the first laser emission unit (122) is aligned at a close distance to the detection field of view. The measurement efficiency of the laser radar on the close-range object is improved.
(ZH) 涉及激光雷达技术领域，具体涉及一种激光发射装置和激光雷达，激光发射装置包括：激光发射阵列(110)、第一激光发射单元组(120)和第一发射光学调整单元组(140)；激光发射阵列(110)包括第一激光发射单元组(120)；第一激光发射单元组(120)包括多个第一激光发射单元(122)；第一发射光学调整单元组(140)包括多个第一发射光学调整单元(142)；第一发射光学调整单元组(140)中的第一发射光学调整单元(142)与第一激光发射单元组(120)中的第一激光发射单元(122)对应设置，用于调整第一激光发射单元组(120)中的第一激光发射单元(122)发出的激光信号的出射方向，使第一激光发射单元(122)发射的激光光束与探测视场在近距离处对准。提高了激光雷达对近距离物体的测量效率。
