Abstract

The invention discloses a liquid crystal based monocular and binocular integrated imaging detection chip which comprises a ceramic shell, a metal support, a heat radiation plate and a monocular and binocular integrated imaging detection framework. The rear portion of the ceramic shell is arranged on the top of the metal support and the heat radiation plate, and the monocular and binocular integrated imaging detection framework is arranged in the ceramic shell and comprises a drive control and image preprocessing module, an area array visible light detector and an area array electric-control liquid crystal imaging micro lens in coaxially sequential arrangement. The area array electric-control liquid crystal imaging micro lens is used for receiving visible light from a top opening of the ceramic shell and focusing the visible light onto the area array visible light detector, and the drive control and image preprocessing module receives external operation signals through a communication and control signal output port and generates drive signals according to the operation signals. The liquid crystal based monocular and binocular integrated imaging detection chip has the advantages of compact structure, convenience in use, easiness in coupling with conventional optical imaging system, high target and environment adaptability and the like.

Description

technical field [0001] The invention belongs to the technical field of imaging detection, and more specifically relates to a liquid crystal-based monocular compound eye integrated imaging detection chip. Background technique [0002] The compound eyes of insects such as flies, dragonflies and bees have multiple parallel imaging detection and the ability to perceive and identify moving targets. With imaging-based optical properties such as focal length, focal depth, focal spot position and size, clear aperture and point spread function, etc., it has a good adaptability to the environment and the target. So far, a variety of high-performance imaging detection devices have been developed by imitating insect compound eyes, such as typical co-located compound eye cameras, compound eye imaging detection architectures based on CCD, CMOS or FPAs, micro-self-focusing crystal cone bionic compound eyes, and multi-eye parallel-based Miniaturized wide field of view and large depth of fi...

Problems solved by technology

[0003] The method developed so far to construct a compound eye imaging detection framework by coupling a specific shape of refractive or diffractive microlenses with a photosensitive array has shown several defects, such as: (1) the arraying of a specific surface profile The microlens only has fixed optical performance, no ability to adjust the focus, adjust the point spread function, and change the field of view, and has poor adaptability to the environment and the target; (2) Each unit imaging microlens in the conventional microlens array can only match limited Large-scale sub-photosensitive arrays have low spatial resolution, image clarity and contrast, weak detail reproduction capabilities, serious lack of image layering, and poor completeness of target images; , to invert the conventional high spatial resolution and large-scale clear image of the target; (4) to achieve imaging focus or focusing needs to be performed through mechanical movement between multiple sets of converging or diverging microlens arrays arranged in cascade, slow response and state transition It takes a long time and has a large inertia, and it needs to be matched with a complex and precise auxiliary drive control device. Due to the intrinsic continuity of the motion posture, it is impossible to perform arbitrary optical state cut-in or jump, and the optical transformation capability is limited; Bionic compound eye structure coupled with photosensitive array chip
