Problems solved by technology

[0002] The fusion of low-light images and infrared images will help to integrate the better target indication characteristics of infrared images and the clear scene information of low-light images, which can adapt to more complex battlefield environments and improve the probability of target discovery. When aiming, it is necessary to adjust the position of the infrared objective lens and the low-light objective mirror surface to meet the clear image. However, during the focusing process, the low-light and infrared images may not overlap, and there may be deviations, which will affect the fusion observation effect. In order to ensure the fusion To observe the effect, it is necessary to ensure the assembly accuracy of the objective lens of the telescope. Therefore, the objective lens assembly method for the fusion type telescope is an important optical technology method. In the existing objective lens assembly method for the fusion type telescope, there are still After the lens frame and lens barrel are machined, the concentricity between the lens and the lens barrel is guaranteed through the matching between the lens frame and the lens barrel, which affects the imaging quality of the fusion telescope

Abstract

The invention provides an objective lens assembling and adjusting method for a fusion type telescope. The objective lens assembling and adjusting method for the fusion type telescope comprises the steps that machining of the excircle and the end face of a lens barrel is conducted by using the center line of a main shaft of a machining lathe as the datum line, and abrasive machining of a gap between a lens frame and the lens barrel is conducted by using the stability of an auto-collimation image of an auto-collimation goniometer as the datum. The dimensional accuracy of the lens frame and the lens barrel is guaranteed through the machining process, the concentricity of an objective lens is guaranteed without the need for selective assembly of the lens frame and the lens barrel, and therefore the imaging quality of the fusion type telescope is improved.

Description

technical field [0001] The invention relates to an objective lens assembly and adjustment method, in particular to an objective lens assembly and adjustment method for fusion telescopes which is particularly suitable for fusion of low-light images and infrared images. Background technique [0002] The fusion of low-light images and infrared images will help to integrate the better target indication characteristics of infrared images and the clear scene information of low-light images, which can adapt to more complex battlefield environments and improve the probability of target discovery. When aiming, it is necessary to adjust the position of the infrared objective lens and the low-light objective mirror surface to meet the clear image. However, during the focusing process, the low-light and infrared images may not overlap, and there may be deviations, which will affect the fusion observation effect. In order to ensure the fusion To observe the effect, it is necessary to ens...
