Artificial compound eye with adjustable large eye curvature, preparation method and application

Abstract

The invention discloses an artificial compound eye with an adjustable large eye curvature, belongs to the field of bionic optical element preparation, and adopts a wet etching assisted femtosecond laser direct writing technology to prepare a hard template with a small eye array inverse structure, and a flexible material can be quickly imprinted into a flexible small eye array film with 100% filling factors by using the hard template; a compound eye lens inner structure with a hollow flat cylindrical hole groove and a microfluidic channel is prepared through femtosecond laser direct writing, and a flexible small eye array film and the compound eye lens inner structure are bonded and integrated to form a planar compound eye structure; deionized water is injected into the fly-eye lens throughthe microfluidic channel, the flexible small eye array film can be rapidly driven to protrude upwards, and the artificial fly eye with the curvature flexibly adjusted by the deionized water injectionamount is obtained. The artificial compound eye prepared by using the wet etching assisted femtosecond laser direct writing technology has the advantages of high efficiency, uniformity and high filling factor, effectively realizes integration of a small eye array and any curvature surface shape, freely regulates and controls the large eye curvature of the artificial compound eye, and the like.

Description

technical field [0001] The invention belongs to the field of bionic optical element preparation, and in particular relates to an artificial compound eye with adjustable big eye curvature, a preparation method and an application. Background technique [0002] With the advancement of science and technology, people's demand for optical, mechanical and electrical integration of optical instruments and equipment is increasing day by day. Artificial intelligence such as drones and micro-robots is developing towards system integration and miniaturization. There is an urgent need to improve the integration and observation capabilities of micro-scale optical components. Inspired by the compound eyes of insects in nature, combined with its small size, light weight, large field of view, and sensitivity to moving objects, people have proposed a corresponding artificial compound eye system. The compound eye is a special visual organ composed of an indefinite number of ommatidia closely...

Problems solved by technology

However, these processing technologies have problems such as low processing accuracy, low filling factor, and complicated processes.

In general, the existing artificial compound eye processing methods have their own advantages and disadvantages, but none of them can meet the needs of high filling factor, small aperture and easy processing at the same time.

At the same time, the curvature of the large eye of the compound eye processed by the above method is fixed and cannot be adjusted, which limits the performance of the device to a certain extent
