Preparation method of bionic PDMS (Polydimethylsiloxane) curved compound eye

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
