Abstract
The invention discloses a liquid crystal wavefront corrector and a packaging method thereof. The packaging method includes: providing a substrate and a cover plate; The two alignment layers perform rubbing alignment; when the rubbing roller performs rubbing alignment on the first alignment layer, the preset area of the first alignment layer corresponding to the frame area is used as the first starting position, and the first alignment layer is The area of the alignment layer corresponding to the light transmission area is rubbed and aligned; when the rubbing roller rubs and aligns the second alignment layer, the preset area of the second alignment layer corresponding to the frame area is used as the second starting point. performing rubbing alignment on the area of the second alignment layer corresponding to the light-transmitting region; and encapsulating a liquid crystal layer between the first alignment layer and the second alignment layer. The technical solution of the invention can greatly improve the alignment uniformity of the liquid crystal wavefront corrector and the thickness uniformity of the liquid crystal layer.
Description
technical field [0001] The invention relates to the technical field of liquid crystal devices, in particular to a liquid crystal wavefront corrector and a packaging method thereof. Background technique [0002] The principle of the liquid crystal adaptive optics system is based on real-time compensation and correction of the distorted wavefront of the incident light of the system, so as to obtain ideal optical imaging. At present, liquid crystal wavefront correctors based on nematic liquid crystal materials are manufactured using mature integrated circuit technology, and have technical characteristics such as high pixel density, low cost, and high correction accuracy. It corrects the wavefront through kinoform technology, Therefore, the correction amount can be compressed within the absolute phase modulation amount of 1λ (λ is the wavelength of the modulated light), and the distortion wavefront with a maximum correction amount of about 10λ can be corrected. [0003] Therefo...
