Embodiment Construction

[0017] The present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

[0018] Implementation steps of the present invention are:

[0019] 1. Preparation of prepolymers, liquid crystal optical performance additives composed of electronically controlled polymer-dispersed liquid crystal materials, which are mixed with chemical materials such as polymers, liquid crystals, light guides, synergistic initiators, and crosslinking agents. Photopolymerization occurs under the action of a 441.6nm He-Cd laser or a 514nm Ar ion laser to form a PDLC material in which liquid crystal droplets are dispersed in a polymer matrix. Under the regulation of the electric field, the optical axis direction of the liquid crystal molecules rotates with the electric field, the effective refractive index of the liquid crystal molecules changes from different to the same as that of the polymer, and the surface of the material changes from scattering...

Abstract

A method for preparing micro lens array controlled by electricity includes preparing polymer scattered liquid crystal material being electrically controlled and transparent ITO conductive film liquid crystal case glass plate being electrically controlled, adding mask and placing electric control system in glass plate array, coating a layer of said scattered liquid crystal material between two glass plates, preparing holographic lens, utilizing mask technique to prepare lens array and utilizing computer to carry out control and calculation for realizing optical interconnection and shuffle function of lens array in order to achieve arbitrary regulation and control of transmission light path.

Description

technical field [0001] The invention relates to a method for manufacturing an optical and electronically controlled lens array, in particular to a method for manufacturing a lens array in which a single lens in an optical microlens array can be controlled by an electric field and has a switching function. Background technique [0002] A single lens can image an object and transform a light beam, and an array of lenses can form a "compound eye" effect. Traditional optical lenses need polishing, grinding and other processes, and at the same time have a large volume, it is very inconvenient to use traditional lens groups to make lens arrays. However, with the development of optoelectronic technology, lens arrays have been actively applied in the fields of optical interconnection, laser scanning, beam shaping, optical communication, adaptive optics, and display technology. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings ...
