Problems solved by technology

[0003] At present, a single lidar only has one scanning method among multiple scanning methods such as single point, pendulum mirror, galvanometer, linear array, and area array, and cannot have two or more scanning methods at the same time.
As the best two scanning methods, linear array and area array scanning cannot be integrated into the same single lidar at the same time
In order to solve the problem that the same laser radar has both linear array and area array scanning modes and their mutual switching, the present invention designs a new type of laser radar linear array and area array switchable grating micro servo system

Abstract

The invention discloses a linear array and area array switchable grating micro-servo system of a novel laser radar (LiDAR). The principle is as follows. In an initial state of the system, the switch is in an off state and a linear array scanning mode exists correspondingly. When a user presses down the switch, the switch is switched to an on state, and the system is switched to an area array scanning mode. When the user presses the switch again, the switch returns to the off state, and the system switches back to the linear array scanning mode. The system integrates the advantages of a lineararray scanning mode and an area array scanning mode, supports the flexible switching of a linear array / area array mode, and meets the requirements of large-field-angle and high-resolution laser radarscanning.

Description

technical field [0001] The invention belongs to the field of laser radar (LiDAR, Light Detection and Ranging, laser detection and ranging system), in particular to a novel laser radar line array and area array switchable grating micro-servo system, which is applied to an airborne radar scanning system. [0002] technical background [0003] At present, a single lidar only has one scanning method among multiple scanning methods such as single point, swing mirror, galvanometer, linear array, and area array, and cannot have two or more scanning methods at the same time. As the best two scanning methods, linear array and area array scanning cannot be integrated into the same single lidar at the same time. In order to solve the problem that the same laser radar has both linear array and area array scanning modes and their mutual switching, the present invention designs a new type of laser radar's line array and area array switchable grating micro servo system.
