Multi-field-of-view bionic ommateum low-light-level imaging system based on multi-micro-surface optical fiber faceplate

Abstract

The invention relates to a multi-field-of-view bionic ommateum low-light-level imaging system based on a multi-micro-surface optical fiber faceplate and belongs to the technical field of optical imaging. By designing the multi-micro-surface optical fiber faceplate and a corresponding optical system and coupling the optical fiber faceplate with a CCD / CMOS image device, imaging of multiple sub-field of views can be achieved on the single image device; meanwhile, because all the field of views of the multi-micro-surface light cone / optical fiber faceplate can be partially overlaid, sub-images can be spliced into an image with a large field of view (>=100 degrees), and target three-dimensional information can be acquired through overlapping portions of all the sub-images. The low-light-level night vision imaging observation system is small in size, light in weight and large in field of view (>=100 degrees); the structure of the system is simplified, and the cost of the system is reduced.

Description

technical field [0001] The invention relates to a multi-field bionic compound eye low-light imaging system based on a multi-microfacet optical fiber panel, which belongs to the technical field of optical imaging. Background technique [0002] The artificial bionic compound eye technology is conducive to obtaining a miniaturized, lightweight, and large field of view imaging system, and can obtain target three-dimensional position information. It can be widely used in large field of view monitoring equipment, rapid target positioning systems and other fields, and has broad application prospects. . Therefore, various artificial bionic compound eye technologies are one of the hot research directions in related fields. [0003] Traditional large field of view imaging systems generally use fisheye lenses or multiple cameras. The fisheye lens has a large volume and weight, serious imaging deformation, and cannot obtain the three-dimensional position information of the target; the...

Problems solved by technology

[0009] In the bionic compound eye imaging system realized by microlens array, the aperture of each lens is very small, some are even in the micron level, which is limited by the precision of optical micromachining and the level of assembly, and the matching detector array also needs special processing , so this kind of compound eye system has very little practical application at present

[0010] In recent years, a domestic company has also proposed a compound eye system structure using a spherical top surface light cone with a lens array (patent publication number: CN102819053A), but the number of lenses in this system structure is large and the size is small, and it is difficult to arrange light between each lens. Diaphragm to ensure that the light between each lens can be isolated from each other without affecting the image quality
