Embodiment 1

[0036] like figure 1 and figure 2 As shown, a device for optical axis consistency detection includes a multispectral light source 11, a multispectral target 10, a collimator, a target multidimensional displacement unit 7, a half mirror 9, an image acquisition unit, and a laser pointer Device 1 and alignment adjustment unit 5;

[0037] The multi-spectral light source 11 can provide a spectrum including all bands of the detected device for illuminating the multi-spectral target 10, and image the multi-spectral target 10 into an infinitely distant visible and infrared target through a collimator;

[0038] The multi-spectral target 10 is a target plate that can pass through all bands of the detected equipment. In this implementation, a ZnS glass target plate that transmits the full spectrum band is selected, and the target cross reticle of the chrome-plated material is etched on the target plate by photolithography technology. Pattern, according to the infrared and TV system te...

Abstract

The invention relates to a device and method for optical axis consistency detection, and belongs to the technical field of measuring instruments. The device is simple in structure, simple in operation, and capable of realizing rapid and efficient detection of multi-optical axis consistency; deviation angle values of other optical axes in detected equipment relative to a certain reference optical axis can be calculated; according to the invention, subsequent adjustment and calibration can be carried out on the detected equipment according to a measurement result, so that a consistency error ofmultiple optical axes is controlled within an allowable range of observing and aiming precision, and the functions of searching, tracking, aiming, ranging, indicating, pointing and the like are ensured to be accurate, stable and reliable.

Description

technical field [0001] The invention relates to a device and method for optical axis consistency detection, belonging to the technical field of measuring instruments. Background technique [0002] With the development of optoelectronic technology, optoelectronic reconnaissance equipment integrating laser ranging, laser guided irradiation, visible light imaging and thermal imaging has been widely used on various weapon equipment platforms, greatly improving the efficacy and capabilities of weapon equipment , has become a key technology for the development of weapons and equipment in various countries. The consistency of multiple optical axes is a key performance indicator of electro-optical reconnaissance equipment. The optical axis consistency of CCD cameras with different fields of view is mainly to ensure that the image positions observed by CCD cameras of different fields of view are consistent, which is convenient for reconnaissance and aiming; The continuity of the ta...
