Portable optical axis detecting system of laser range finder

Abstract

The invention provides a portable optical axis detecting system of a laser range finder, which comprises a slanting square prism component (3), a target plate component (9) and a small-diameter reflector (12), wherein the target plate component comprises a target plate (8) fixedly connected to the shaft end of a support cylinder body through a target plate clamping ring (10); the slanting square prism component (3) comprises a slanting square prism bracket (2) with a receiving light through hole (7) formed in the center, and a slanting square prism table (1) fixedly connected above the receiving light through hole; a front light through hole (6) and a rear light through hole (5) are fabricated in diagonal lines at two ends of a rectangular frame groove of the slanting square prism table respectively; and a slanting square prism (17) is arranged in the rectangular frame groove of the slanting square prism table. When passing through a first 45-degree reflecting surface of the slanting square prism, an aiming optical path of the laser range finder generates 90-degree refraction, is refracted to another 45-degree reflecting surface, and generates 90-degree refraction again, and the optical path after the refraction is parallel to that before the refraction.

Description

technical field [0001] The invention belongs to a device for debugging, checking and correcting the optical axis of a laser distance measuring machine in the field environment. Background technique [0002] As a distance sensor, the laser range finder generally includes three systems: the transmitting system, the receiving system and the aiming system. Whether the parallelism of the optical axes of these three systems meets the requirements is one of the keys to whether the technical indicators of the entire range finder can be achieved. one. Generally, the distance between the optical axes of the repetition-frequency air-to-air laser range finder is relatively large. Taking the XX model laser range finder as an example, the maximum distance between the optical axes of the aiming system and the transmitting system is as follows: Figure 4 Shown in d (d is 268mm). To meet the requirements of three optical axis adjustments, the optical aperture of the reflector should include...

Problems solved by technology

Such reflectors are bulky, heavy and inconvenient to carry and install, and it is impossible to use them in the field

Therefore, the debugging of the optical axis of the previous laser range finder is generally completed in the optical adjustment room, but after the laser range finder is delivered for use, its working environment is mostly in the field. Once a fault occurs, repairs or routine maintenance need to be done in the field. However, as long as the adjustment of the optical axis is involved, it is impossible to carry out in the field. Usually, the laser range finder is returned to the factory or sent to the repair station of the military region for repair. The repair cost is not only high, but also wasting time
