Abstract

一种激光雷达及设备，包括：壳体(100)，限定出发射腔室(210)以及接收腔室(220)；激光发射装置，设置于发射腔室(210)，用于向第一目标区域发射激光束；多个激光接收装置，设置于接收腔室(220)，多个激光接收装置可接收第二目标区域内反射的激光束，第一目标区域与第二目标区域至少部分重合；第二目标区域由多个子探测区域组合而成，每个子探测区域均小于第一目标区域且与第一目标区域至少部分重合，各激光接收装置一一对应接收各子探测区域内的反射的激光束。激光雷达将激光发射装置以及激光接收装置独立设置，且激光接收装置的数量为多个，相对于仅有一个激光接收装置的结构而言，增加多个激光接收装置能够增大探测视角，从而减小激光雷达的探测盲区。
