Abstract

The invention discloses a field-of-view matching device of astronomical positioning laser radar, which comprises a computer, and further comprises a driver, an angle adjusting frame, a laser, a reflector, a receiving telescope, a spectroscope, a CCD camera, a receiving optical fiber and a signal detection system. The invention further discloses a field-of-view matching method for the astronomicalpositioning laser radar. Through monitoring and adjustment of the laser beam orientation, the data inversion precision of the laser radar is improved, the data coherence of the laser radar is effectively improved, the device and method are suitable for a coaxial or off-axis laser radar system, and an effective scheme is provided for accurate adjustment of the laser radar.

Description

technical field [0001] The present invention relates to the field of laser radar automatic control, in particular to a field of view matching device for astronomical positioning laser radar, and also relates to a field of view matching method for astronomical positioning laser radar, which is used for precise positioning of atmospheric detection laser radar and star map . Background technique [0002] Laser has the characteristics of good monochromaticity, high brightness, and excellent directivity. The lidar formed by the interaction between laser and the atmosphere has the advantages of high spatial and temporal resolution, high detection sensitivity, and the ability to distinguish detected species. It is widely used Applied in the field of atmospheric detection. The atmospheric detection lidar system is composed of three parts: laser emission system, telescope receiving system, and signal detection system. According to whether the laser optical axis coincides with the o...
