Abstract

The present invention relates to a wide-angle imaging device based on a concentric spherical objective lens, which includes: a concentric spherical objective lens with an objective field of view; a small field of view field mirror system, including: a field lens and a corresponding detection device arranged on the imaging side of the field lens device; the optical axis of the field lens passes through the center of the sphere of the concentric spherical objective lens; the field of view of the field lens is a part of the field of view of the objective lens; The system rotates around the spherical center of the concentric spherical objective lens; the swing mechanism has at least two scanning positions; wherein, the small field of view mirror system collects images at the at least two scanning positions to obtain at least two A sub-image, the at least two sub-images are spliced ​​to obtain a single-frame full-width image. The wide-angle imaging device of the present invention is compact in structure and has a large field of view imaging range.

Description

technical field [0001] The invention relates to the technical field of wide-angle imaging, in particular to a wide-angle imaging device based on a concentric spherical objective lens. Background technique [0002] Compared with radar, photoelectric detection equipment has the characteristics of high resolution and passive detection, so it is widely used in occasions that require higher resolution. The resolution of the optical system of traditional photoelectric detection equipment and the field of view have a relationship as shown in formula (1): [0003] N·d=f·tanθ (1) [0004] Among them, N represents the number of pixels of the photoelectric sensor in a certain direction, d represents the image source spacing size of the photoelectric sensor in the corresponding direction, f is the focal length of the optical system, and θ is the field angle of the optical system in the corresponding direction. It is easy to know from formula (1) that when the photoelectric sensor sele...
