Abstract

The invention relates to a preparation technology of an artificial compound eye, in particular to a preparation method of a PDMS (Polydimethylsiloxane) material artificial compound eye. The PDMS material artificial compound eye is prepared by adopting a PDMS-silicone oil swelling method, and the method comprises the following steps: 1) cleaning a sample; 2) through femtosecond laser modification, an ablation crater is formed on the surface of the curved glass substrate; (3) a curved surface wet etching process is carried out, and a curved glass compound eye template is formed through ultrasonic water bath chemical corrosion; 4) preparing an artificial compound eye structure of the PDMS material through a reverse mold; and 5) preparing the artificial compound eye made of the PDMS material through a PDMS-silicone oil swelling method. The problems that an artificial compound eye surface structure prepared in the prior art is poor in durability, prone to losing hydrophobic capacity and insufficient in anti-fog capacity are solved, and the artificial compound eye prepared through the method can meet the transparency requirement and has the waterproof and anti-fog capacity and good durability at the same time.

Description

technical field [0001] The invention relates to a preparation technology of artificial compound eyes, in particular to a preparation method of PDMS material artificial compound eyes. Background technique [0002] Compound eyes exist in many insects in nature. Compound eyes are composed of thousands of ommatidium, each of which is a separate imaging unit, which endows compound eyes with a unique imaging performance that is different from monocular ones. Compound eyes have the characteristics of high-resolution imaging, wide field of view, and high sensitivity to moving objects, which have broad application prospects in the fields of robot vision, medical endoscopy, and motion monitoring. At present, many processing methods have been developed for biomimetic preparation of compound eye structures and functions, such as femtosecond laser wet etching, thermal reflow, and photolithography-based methods. Based on the above methods, artificial compound eyes with certain waterproof...
