Problems solved by technology

[0004] The quality of the orthogonality adjustment of the laser mirror directly determines the effect of laser interference countermeasures. If the adjustment is not good, it will lead to inaccurate irradiation positions and low tracking accuracy.

Abstract

The invention relates to a reflector adjusting method of a laser rotary table. The method comprises the following steps that 1) a third reflector is adjusted by fixing a first tool reflector at the left end surface of the laser rotary table and adjusting the third reflector so that a reflection image coincides with a cross wire of a parallel light pipe; 2) a second reflector is adjusted by mounting the second reflector at the left end surface of the laser rotary table, pasting a third tool reflector to the front end surface of a second reflector fixing rack so that a reflection image of the third tool reflector coincides with the cross wire of the parallel light pipe; 3) a first reflector is adjusted by arranging the first reflector on a horizontal platform and placing a second tool reflector under a central hole of the first reflector that a reflection image coincides with the cross wire of the parallel light pipe; and 4) the first reflector is mounted by placing the parallel light pipe in front of the first reflector and using left and right pentaprisms, so that light is reflected into a sighting piece of a TV set and the sighting piece is adjusted to coincide with the cross wire of the parallel light pipe.

Description

technical field [0001] The invention relates to a reflector adjustment method, in particular to a reflector adjustment method for a laser turntable, which is used for a display console required by the navy to resist harsh environments. Background technique [0002] Since infrared-guided air-to-air or air-to-ground missiles are mostly medium-wave infrared, the laser jamming countermeasure system must work in the medium-wave infrared band to achieve the goal of jamming and blinding these incoming missiles. Because in order for the laser launch system to interfere and blind the infrared detectors of incoming missiles, it must have an optical path that can lock and track the target stably. However, due to the large inertia characteristic of the two-axis tracking turntable, it is difficult to achieve ultra-high precision and stable tracking of the target. Therefore, adding a small-inertia fine tracking turntable to the two-axis rough tracking turntable can provide laser emission ...
