Embodiment Construction

[0053]Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0054] The basic principle of laser radar is that the laser emits laser light, which is collimated by the transmitting optical system and then emitted. After the laser hits the object, it is reflected back to the receiving optical system of the laser radar and converted into an electrical signal. According to whether the laser transmitting optical system and the laser receiving optical system are coaxial, the optical system of lidar can be divide...

Abstract

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.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of laser radar, and in particular to a laser emitting device, laser radar and intelligent sensing equipment. Background technique [0002] With the development of technology, lidar is widely used in the field of intelligent equipment such as automatic driving, intelligent robot navigation, and unmanned aerial vehicles, and is applied to scenarios such as environmental detection and space modeling. Lidar is a radar system that emits laser beams to detect the position, speed and other characteristic quantities of target objects. The transmitted signals are compared and processed to obtain relevant information of the target object, such as target distance, azimuth, height, speed, attitude, shape and other parameters. [0003] The inventors of the present application found in the research process that the off-axis laser radar, in order to obtain long-distance ranging capabilities, has the ...
