Description

technical field [0001] The invention belongs to the technical field of imaging detection, and more specifically relates to a full-color compound eye imaging detection chip based on monocular intussusception. Background technique [0002] The compound eyes of insects such as flies, dragonflies, and bees have undergone hundreds of millions of years of evolution and perfection in nature, and gradually evolved into an array of small / miniature multiple photosensitive and visual structures with unique imaging capabilities. It has the characteristics of large depth of field, multiple apertures in parallel, super large field of view, and keen perception of moving targets. So far, a variety of bionic compound eye structures have been developed at home and abroad.

Problems solved by technology

[0003] Although the bionic compound eye technology has shown broad development prospects in the fields of scientific research and engineering applications, the existing bionic compound eye technology is restricted by factors such as micro-nano optical manufacturing technology, area array photosensitive device technology, and optical-electrical coupling integration methods. It is difficult to make a qualitative breakthrough in the detection capability in the short term

Its defects are mainly as follows: (1) The processing and integration technology of flat, curved or even deformable end faces or flexible refraction / diffraction microlens arrays are still insufficient; Typical hexagonal high-order curved surfaces, etc., require extremely high-cost ultra-fine processing methods, the light transmission or numerical aperture of the single eye is small, and the vision is poor; In the case of an area array photosensitive structure, the unit microlens can only be coupled with a sub-photosensitive array with a limited array size, which is restricted by the imaging capability of a single eye, resulting in a narrow field of view, low image clarity, poor contrast, weak detail reproduction, and serious image layering Insufficient and poor image quality caused by low image integrity of the target; (4) The angular resolution of the target’s outgoing beam is low, and the angular detail measurement and reproduction of the target pose is poor; (5) Feature extraction and motion behavior calculation of the target It needs to be supported by complex algorithms that take up a lot of electronic resources; (6) It needs to be equipped with special optical systems, etc.

In other words, the existing bionic compound eye imaging system will not be able to reconcile the inherent characteristics of the combination of large-scale micro-optical structures and multi-monocular photosensitive detection architectures, the conflict between high spatial resolution and high image quality, and the lack of angular resolution. contradiction
