Embodiment Construction

[0040] A method for preparing a bionic PDMS curved surface compound eye, comprising the steps of:

[0041] (1), preparation of PDMS micro-convex lens mold 7:

[0042] Step 1: Take the first mask 2 whose shading part is several small circles 1 with a diameter of 100um, and several small circles 1 are evenly distributed within the large circle with a diameter of 1cm, wherein: the distance between adjacent small circles is 10um And the centers of three adjacent small circles are connected together to form an equilateral triangle;

[0043] Step 2: take the first circular substrate 3 with a diameter of 4 inches and carry out surface pretreatment at 180 0 Bake 30min on the C baking table and be down to room temperature again; Be coated with the AZ4620 photoresist that one deck thickness is 15um on the first circular substrate 3 and place on 80 0 Bake on the baking tray C for 90 minutes and then drop to room temperature; put the first circular substrate 3 and the first mask plate 2...

Abstract

The invention relates to a bionic curved compound eye, in particular relates to a preparation method of a bionic PDMS (Polydimethylsiloxane) curved compound eye. The invention solves the problem that the bionic curved compound eyes in prior arts are large in volume, small in field of view and low in practicability. The preparation method of the bionic PDMS curved compound eye comprises the following steps: preparing a PDMS micro convex lens model; preparing a PDMS grid model; preparing a PDMS peripheral wrapping model; bonding the PDMS micro convex lens model and the bottom of the PDMS grid model; inserting an optical fiber in a cylindrical cavity of the PDMS grid model; bonding the PDMS peripheral wrapping model on the outer circumference of the PDMS grid model to form a cavity between the PDMS grid model and the PDMS peripheral wrapping model; and bending the PDMS micro convex lens model by pressing the cavity so as to obtain the compound eye. The compound eye prepared in the invention has the advantages of low cost, simple manufacturing, micron dimension and nanometer precision and can be widely applied to the field of three-dimensional imaging detection.

Description

technical field [0001] The invention relates to a compound eye with a bionic curved surface, in particular to a method for preparing a compound eye with a bionic PDMS curved surface. Background technique [0002] Bionics has always been an important source of inspiration for scientists. Over the years, people have obtained inspiration and invented countless scientific and technological achievements through the study of animal shapes and organs. From the long tail of a dragonfly to a helicopter, from the echolocation of a bat to radar, from the way a firefly glows to a fluorescent lamp, and so on. Compound eyes are large and protruding photoreceptors located on both sides of the insect's head. They have the characteristics of large field of view, light weight, high sensitivity, and sensitivity to polarized light. Therefore, bionic research on them will have great potential in imaging detection and other fields. Great application prospects. At present, although scientists ha...
