Abstract

The invention belongs to the technical field of optical liquid crystal zoom, and particularly relates to a zoom lens. The electronic control type zoom lens comprises a circuit control part and a zoompart, the zoom part comprises two nematic phase liquid crystal devices, each nematic phase liquid crystal device comprises a nematic phase liquid crystal box and two electrodes, and the two electrodesare arranged on the two opposite sides of the nematic phase liquid crystal box respectively. The length directions of the two electrodes are consistent with the optical axis direction of the nematicphase liquid crystal box; the optical axes of the nematic phase liquid crystal boxes of the two nematic phase liquid crystal devices are perpendicular to each other; the circuit control part controlsthe two electrodes of each nematic phase liquid crystal device through output voltage values, so that potential difference is generated on the two sides of a nematic phase liquid crystal box of each nematic phase liquid crystal device, and electric control zooming is achieved. According to the invention, an E light part in a light field can be focused, and an O light part can also be focused.

Description

technical field [0001] The invention belongs to the technical field of optical liquid crystal variable focus, and in particular relates to a variable focus lens. Background technique [0002] Existing liquid crystal variable focus systems are all to be carried out only to the E light (abnormal light) part in the light beam at present, but have no zoom effect to the O light (normal light) part in the light beam. Therefore, after the light field intensity passes through the liquid crystal zoom system, part of the intensity will be lost, which affects the utilization rate of energy. Contents of the invention [0003] The present invention aims at the technical problem that the existing liquid crystal variable focus system only performs the zoom effect on E light, resulting in the loss of light intensity, and aims to provide an electronically controlled variable focus lens. [0004] The electronically controlled variable focus lens includes a circuit control part and a zoom p...
