Abstract

The invention discloses a multi-degree-of-freedom omni-directional laser radar which comprises a laser receiving and transmitting module, a direct current motor, a conveying belt, a data processing chip, a stable support, a radar module base, a flange coupling, a conductive slip ring, a bearing support, a bearing and a stepping motor. The structure is used for acquiring the environment point cloud and improving the scanning efficiency. By means of the detachable stepping motor and other components, the arrangement position can be adjusted within a certain range, and the requirements of structures of different sizes in engineering are met; and the assembly process is simple, the assembly period is short, and a large amount of manpower and time expenditure are saved.

Description

technical field [0001] The invention belongs to the field of electronic sensors, and in particular relates to a multi-degree-of-freedom omnidirectional laser radar structure. Background technique [0002] Radar using lasers as radiation sources. Lidar is the product of the combination of laser technology and radar technology. It is composed of transmitter, antenna, receiver, tracking frame and information processing. Transmitters are various forms of lasers, such as carbon dioxide lasers, neodymium-doped yttrium aluminum garnet lasers, semiconductor lasers, and wavelength-tunable solid-state lasers; the antenna is an optical telescope; the receiver uses various forms of photoelectric radar, such as photoelectric multiplication Tubes, semiconductor photodiodes, avalanche photodiodes, infrared and visible multi-element radar components, etc. Lidar adopts two working modes of pulse or continuous wave, and the detection methods are divided into direct detection and heterodyne...
