Embodiment Construction

[0014] The present invention describes a manufacturing method of an artificial bionic compound eye. The technical solution is different from the existing artificial bionic compound eye manufacturing method, and the femtosecond pulse two-photon polymerization technology is used to manufacture an artificial compound eye structure. As the only two-photon polymerization technology that can precisely control and fabricate any three-dimensional micro-nano structure, it undoubtedly has unique advantages in fabricating complex artificial compound eyes. Combined with the recently developed ultraviolet nanoimprinting (UV-NIL) and soft lithography technology, polydimethylsiloxane PDMS (Poly-Dimenthylsiloxane) can be used to fabricate a biologically similar three-dimensional polymer optical system that breaks through the traditional framework. This breakthrough in exploratory research will have broad application prospects in many fields of optical applications, such as data storage and rea...

Abstract

The invention discloses a method for manufacturing artificial bionic compound eyes, comprising the steps of: firstly using femtosecond pulse bi-photon polymerization method to manufacture an inversioncurved surface micro lens mold; using ultraviolet nano impressing to manufacture into a three-dimensional curved surface micro lens template; then manufacturing an elastic mold on the three-dimensional curved surface micro lens template; sequentially accommodating photosensitive resin in the elastic mold, heating for baking into a photosensitive polymer mold with opposite polarity; and finally using the lens to focus ultraviolet lights and right irradiate to the photosensitive polymer mold placed on a substrate, manufacturing a light transmission channel by self-writing waveguide method, andmanufacturing into an artificial bionic compound eye. The invention overcomes limit of photoetching technology in aspect of three-dimensional micro-processing, improves processing precision of micro lens, can effectively reduce manufacture cost, enhance mass production capacity, and further promote application of artificial compound eyes in medical science, industry, military and other fields.

Description

technical field [0001] The invention relates to micro-nano processing technology, in particular to a method for manufacturing bionic compound eyes through micro-nano processing technology, which belongs to the interdisciplinary research of multiple technical fields such as micro-nano processing, material science, bionics and the like. Background technique [0002] The compound eye system in nature is a very wonderful visual imaging system. For example, the compound eyes of bees are composed of thousands of small eyes with different receiving directions arranged in a spherical surface. Each ommatidium consists of a light-refracting lens, a crystal cone, a waveguide sensing rod, and a light receiver. Each ommatidium in this omnidirectional compound eye system can independently receive very small angles of light, while the entire compound eye has a very wide range of viewing angles. Artificial compound eyes have attracted extensive research interest due to the many potential ...
