Problems solved by technology

One is that the space provided by the prism to the display device is narrow, resulting in a small display field of view, only 1 / 3 of the field of view of the other optical path. It can only display simple characters such as a row of four-digit characters, etc., and cannot achieve a large field of view. graphic display
Second, because the spectroscopic film is far away from the normal incidence, the transmittance of the system is less than 35%, the brightness of the displayed image is extremely low, and the product cannot be used during the day
The imaging lens group has narrow space, simple structure, poor imaging quality, and unclear additional graphic information, making it difficult to see characters

Embodiment Construction

[0025] See figure 2 , a multi-spectral section multi-receiver light splitting and image combining prism system that can superimpose and display graphic information, including a roof prism 4 and an isosceles prism, is characterized in that the isosceles prism is set to consist of an isosceles prism 2 and a right-angle prism A1 and right-angle prism B3 are combined, wherein right-angle prism A1 and right-angle prism B3 have the same shape and are symmetrically attached to the two isosceles surfaces of isosceles prism 2 respectively to form beam splitting surface A17 and beam splitting surface B19; The reflection of the prism 2 and the imaging lens 10 parallel to the reflection and transmission surface 18 are provided on a distance from the reflection surface 18 of the prism 2, and a plane reflection mirror 9 and the imaging lens A 8 parallel thereto are set; Above the reflective surface 15, the image of the display 6 is reflected to the imaging lens A8 along the incident optica...

Abstract

The invention discloses a multi-spectral and multi-receiver beam splitter and coincidence prism system capable of superposing and displaying graphic and text information. The multi-spectral and multi-receiver beam splitter and coincidence prism system comprises a roof prism (4) and an isosceles prism. An isosceles prism body (2), a right-angle prism A (1) and a right-angle prism B (3) are combined with one another to form the isosceles prism. The multi-spectral and multi-receiver beam splitter and coincidence prism system has the advantages that different spectra can be parallelly processed differently, and the additional graphic and text information can be superposed on image surfaces and can be quite clearly displayed in large visual fields.

Description

technical field [0001] The invention belongs to the technical field of a multi-spectral multi-receiver light splitting and image combining prism system capable of superimposing and displaying graphic information. Background technique [0002] At present, the prism in the imaging optical system mainly plays the role of the erect image. There are three main types of traditional erecting prisms: Porro prisms, Schmidt-Specific Han prisms, and Abbe prisms. In the traditional optical system without electronic system, they can also play the role of positive image, and the modern optoelectronic products with increasingly complex optics hope to integrate multiple functions in a smaller volume, such as information processing of multi-spectral bands, For the target processing of multiple signal sources, at this time, the traditional prism has great limitations and cannot meet the requirements. [0003] Existing erecting prism groups are used in imaging optical systems, such as optica...
