Problems solved by technology

Since the laser transmitting antenna only performs aberration correction for the laser wavelength when designing the optical system, the imaging quality is poor at the wavelength of visible light (such as d-light or D-light) or the laser wavelength of He-Ne laser (0.6328μm)
Therefore, when debugging a laser transmitting antenna with a wavelength of visible light or a wavelength of 0.6328 μm, it is not easy to interpret the optimal coincidence position of the focal plane of the objective lens and the focal plane of the eyepiece, which inevitably brings about debugging errors

Abstract

The invention relates to an antenna modulating method and equipment for a 1.064 mu m laser distance measurement machine. It aims at the working wave length of the laser distance measurement machine, with parallel light ocular incident coming from the emitting antenna, modulating the focal surface and repetition of the focal surface of the ocular, when the object lens overlaps with the focal surface of the object lens and ocular lens, with beam from the object lens as parallel light.

Description

[0001] Technical field: The present invention relates to a method and debugging equipment for debugging the transmitting antenna of a 1.064 μm laser range finder. Background technique [0002] The radiator of the 1.064μm laser range finder emits a laser radiation beam, which is emitted after the beam is expanded by the transmitting antenna. The laser beam irradiates the target and produces diffuse reflection. The reflected light is focused on the photodetector by the receiving antenna. After being processed by the receiving circuit, Calculate the distance from the target to the machine. [0003] The beam divergence angle of the laser beam pulse output by the laser radiator is relatively large, and the beam must be expanded through the laser transmitting antenna to narrow the beam divergence angle of the laser beam pulse in order to increase the operating distance. [0004] The optical system of the laser transmitting antenna belongs to the telescopic system, which is composed ...
