Optical axis debugging system and method of laser range finder

Abstract

The invention discloses an optical axis debugging system of a laser range finder. The optical axis debugging system comprises a laser, an illumination light source and a CCD camera with a CCD lens, wherein the laser is connected with an emission optical system, and a computer is connected between the CCD camera and the laser. The optical system is connected with the receiving optical system, and the receiving optical system is connected with a detector module, and an attenuating film, a right angle prism and a corner cube prism are arranged in front of the receiving optical system. The invention also discloses a debugging method. The optical axis debugging system can monitor the sharpness of the target surface of the detector assembly in real time, adjust the position of the detector assembly to the optimal position by the adjusting device, and direct the laser spot to the target surface of the detector assembly for optical axis debugging, so that the system is visual and efficient.

Description

technical field [0001] The invention belongs to the field of laser technology, and relates to a system for adjusting an optical axis by combining a near-infrared camera and a corner cube prism, and an adjustment method, which is applicable to various laser optical axis adjustment systems. Background technique [0002] The laser of the laser range finder emits a laser beam, expands the beam through the optical system, and exits to the measured target. The laser beam irradiates the measured target and produces diffuse reflection. The reflected beam is focused on the photodetector through the receiving optical system, and processed by the circuit. After that, the target distance information is calculated. [0003] The "optical axis" of the laser rangefinder is different from the optical axis of general optical instruments, it actually refers to two axes: the optical axis of the laser emitting optical system and the optical axis of the laser receiving optical system. When desig...

Problems solved by technology

The main disadvantages of this method are: first, the use of manual observation and measurement is limited by subjective factors, and the error is large

Second, it is necessary to manually adjust the aiming mechanism of the rangefinder, which is repeated many times and the work efficiency is low

[0006] The disadvantages of the above-mentioned schemes are: they all use analog light sources to calibrate the optical system, the calibration accuracy is low, the system is complicated, and it is not conducive to debugging
