Visible light high resolution double-field of view charge-coupled device (CCD) lens

Abstract

The invention relates to a visible light high resolution double-view-field charge-coupled device (CCD) lens which comprises a front group lens, a variable focal length group lens, a rear group lens and a shell body. An outer ring of the shell body is connected with a view field converting and driving device through a connecting base. A first cover plate and a second cover plate are arranged in the view field converting and driving device. A guide pillar is arranged between the first cover plate and the second cover plate. A first coil cover is connected with the first cover plate and a second coil cover is connected with the second cover plate. A first coil is arranged in the first coil cover. A second coil is arranged in the second coil cover. A first connecting shaft is connected with a transmission rod in a rotating mode in the view field converting and driving device. The lower end of the transmission rod is connected with the guide pillar through a second connecting shaft. The transmission rod is connected with the variable focal length group lens and drives the variable focal length group lens to move left and right in the shell body. The visible light high resolution double-view-field CCD lens has the advantages of being high in quality and definition of images, and capable of quickly responding to light energy changes of environment, being provided with a variable view field, not only finding a target in a large view field, but also recognizing the target in a small view field.

Description

technical field [0001] The invention relates to a visible light high-resolution dual-view field CCD lens. Background technique [0002] In the seeker system of the small missile-mounted weapon system, in order to ensure the angle measurement accuracy of the system, there must be an image sensor with reliable work and clear imaging, which receives, gathers and converts the optical information of distant targets into image signals. The optical system is one of the core components of the optical sensor, and its high-performance imaging quality enables the system to achieve long-distance and high-precision tracking capabilities. [0003] In modern warfare, tactical missiles are required to respond quickly, stably, and remotely. Therefore, the optical system must be able to find targets in a large field of view and identify targets in a small field of view. It is required that this type of optical system has a variable field of view, small size, light weight, wide range of tempe...

Problems solved by technology

[0004] At present, this kind of optical system in China has low resolution, large volume, and heavy weight, and does not have the functions of fast switching dual-field of view and automatic diaphragm light intensity control; in some cases, the special environment will affect the angle measurement accuracy of the system and Image clarity has a certain degree of impact
