The invention relates to a method and system for sector scanning of coherent LIDAR with collimated beams. In one embodiment, a device is provided that includes a LIDAR system having an array of waveguides arranged in a first plane. The array of waveguides is configured to generate a plurality of beams, wherein each beam is emitted from a respective waveguide in the array. The apparatus also includes a collimator configured to shape the plurality of beams into a collimated beam sector having an angular spread in a first plane. In addition, the apparatus includes a polygon scanner configured to adjust a direction of the sector in a second plane different from the first plane. The invention further provides a method adopting the equipment.
本发明涉及用于利用准直射束扇形扫描相干LIDAR的方法和系统。提供了一种设备,该设备包括LIDAR系统,该LIDAR系统具有布置在第一平面内的波导阵列。该波导阵列被配置为生成多个射束,其中每个射束从该阵列中的相应波导发射。该设备还包括准直器,该准直器被配置为将所述多个射束成形为在第一平面内具有角扩展的准直射束扇形。另外,该设备包括多边形扫描器,该多边形扫描器被配置为调整扇形在与第一平面不同的第二平面内的方向。还提供了一种采用该设备的方法。
