Liquid-crystal lens system and forming method

Abstract

A liquid crystal lens system is prepared as arranging multiple pixel point on liquid crystal panel to form diffraction lens fringe pattern on said liquid crystal panel, carrying out control and regulation on pattern formed at said liquid crystal panel by control circuit through a processor for making said pattern be a variable diffraction lens fringe pattern and for making liquid crystal lens be a diffraction lens of focal distance adjustable type.

Description

【Technical field】 [0001] The invention relates to an optical lens, in particular to a liquid crystal lens system. 【Background technique】 [0002] Lenses are basic optical components that can be found everywhere in optical instruments and equipment. With the development of optical technology, the requirements for lenses are getting higher and higher: continuously variable focal length of lenses, lenses with large focal lengths, and small aberrations. Either way, meeting the requirements will make the optical system large and complex. [0003] Microlens is also an important optical device. At present, the traditional manufacturing methods mainly include particle exchange method, compression molding method, photosensitive glass thermoforming method and photoresist thermoforming method. Due to the limitations of the materials used and the traditional technology, the microlenses made by these methods have a common feature, that is, the lens has only one focal length. To obtain...
