Embodiment Construction

[0011] see figure 1 , the digital low-light sight optical system of the present invention, successively constitutes the main optical path by objective lens system, image intensifier 5, light combining prism 6, image transfer system, beam splitting prism 7 and eyepiece system. The objective lens system adopts a front group lens consisting of the first single positive lens 1 and the first doublet lens 2, and a five-piece structure formed with the single positive lens 3 and the single negative lens 4. The objective lens system of this structure can both It meets the achromatic and high-resolution image quality requirements of wide beam, and has the advantages of small size and light weight. The image relay system adopts a seven-chip double Gaussian structure, which can effectively eliminate the system's advanced aberrations and vertical axis aberrations, and ensure the system's excellent image quality; adopt the design idea of ​​a shared image relay system, and the CCD relay syst...

Abstract

The invention discloses a digital low-light sighting telescope optical system which comprises a main optical path which is formed by an object lens system, an image intensifier and an ocular lens system, wherein a light composition prism, an image rotation system, a light splitting prism and a CCD relay system are arranged between the image intensifier and the ocular lens system, the light composition prism, the image rotation system and the light splitting prism are positioned on the main optical path in order, the light composition prism is cooperated with an OLED display apparatus, an OLED display surface and an image intensifier fiber panel position are in conjugation, the OLED display surface and an image intensifier image plane are combined to a main channel of a sighting telescope, and the CCD relay system and the light splitting prism are in cooperation. Apart from a sighting function of a common sighting telescope, the sighting telescope also has functions of television shooting, video image and aiming partition superposition, transmission of an acquired video to a line concentration controller in a wireless transmission mode, display of the video through a display apparatus and the like, and interoperability and cooperation capability between users are effectively raised.

Description

technical field [0001] The invention belongs to the field of optical technology, in particular to a digital low light sight optical system. Background technique [0002] The existing low-light sights are all direct-view low-light sights, which only have the function of observing and aiming at the target personally by the observer. The use limitations are large, and it is impossible to realize cooperation and real-time communication with others, and it is not suitable for modern digitalization. , Information needs. Contents of the invention [0003] In order to solve the above-mentioned defects in the prior art, the object of the present invention is to provide a digital low-light sight optical system, so that the sight can not only have the observation and aiming function that the common sight has, but also have the functions of TV camera, video image and aiming analysis. The function of plan superimposing, wirelessly transmitting the collected video to the hub controller...
