Abstract

The invention provides an artificial bionic compound eye preparation method based on atmospheric pressure cold plasma micromachining. The artificial bionic compound eye preparation method comprises the following steps of spin-coating a layer of photoresist on a substrate, etching the photoresist by adopting atmospheric pressure cold plasma jet, and obtaining a planar concave array structure on thephotoresist after etching, preparing a demolding isolation layer on the upper surface of the planar concave array structure obtained after etching, spin-coating a layer of optical transparent material on the isolation layer, and curing the optical transparent material to form a transparent film, and stripping the cured transparent film to obtain the compound eye lens with the planar convex arraystructure. According to the method, a mask plate is not needed, and the artificial bionic compound eye structure can be obtained through hot-pressing deformation after one-time mold reversing; compared with a traditional micro-lens machining process, the method has the advantages of simple process, low cost, high copying precision and the like.

Description

technical field [0001] The invention relates to the field of optical bionics, in particular to an artificial bionic compound eye preparation method based on atmospheric pressure cooling plasma micromachining. Background technique [0002] Insect compound eyes in nature have the characteristics of small size, wide field of view and high sensitivity. The artificial bionic compound eye developed based on animal compound eyes has potential application in large field of view monitoring, fast target tracking and missile guidance. In recent years, with the development of micro-nano processing technology, femtosecond laser and thermal reflow are mostly used in the preparation of compound eyes. [0003] Among them, Liu H et al. described the method of femtosecond laser processing artificial bionic fly-eye lens in "Fabrication of bioinspired omnidirectional and gapless microlens array for wide field-of-view detections" Applied Physics Letters, 100(13), 133701(2012), It can be seen t...
