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...
