Laser reception debugging method and apparatus

Abstract

The invention relates to the optical adjusting field of a laser range finding machine, and specifically relates to a laser reception debugging method and apparatus. The laser reception debugging method comprises adjusting a reception light path; performing convergence and at least two-level replication for a laser echo signal generated after reflection of the signal emitted from the laser range finding machine through a detection object, and converging the laser echo signal at the photosensitive surface position of the detector eventually; setting an endoscope which can convert the invisible light into visible light, at the position of the photosensitive surface of the detector; and then adjusting the detector. The laser reception debugging method and apparatus can utilize the endoscope to display the invisible light as the visible light so that visual adjusting of a laser optical axis can be realized and accurate adjusting of the light path can be realized. The laser reception debugging method and apparatus can solve the problem about offset of the optical axis because of blind adjusting of laser optical axis, optical component machining error and adjusting error of an assembling staff, and has the advantages of being simple in operation, having no requirement for the skill level and the experience of workers, reducing the adjusting time, effectively improving the adjusting accuracy, and being able to realize accurate and effective adjusting of the laser optical axis.

Description

technical field [0001] The invention relates to the field of optical adjustment of laser distance measuring machines, in particular to a laser receiving and debugging method and a debugging device. Background technique [0002] At present, the laser receiving sensitivity adjustment mostly adopts the method of passing through the axis of visible light, but after the mechanical optical axis is passed through, when installing the optical parts, it is necessary to use a light source with a wavelength of 1064nm to adjust the product, and the light with a wavelength of 1064nm is invisible Yes, and the adjustment and processing errors of the optical lens will also cause a certain amount of offset of the optical axis, resulting in a large change in the optical axis of the machine that uses visible light in the early stage. The photosensitive surface of the detector is generally only 0.5-0.8mm in size. To make the system light spot converge on the center of the detector surface, it c...

AI Technical Summary

Problems solved by technology

Since the photosensitive surface of the detector is too small, and the adjustment direction cannot be determined during the debugging process, very skilled workers are required to adjust the product, and it takes two or three days

The existing debugging method is time-consuming and laborious, and the adjustment accuracy is difficult to meet the technical requirements, and it is not convenient for fault repair and field maintenance
