The forming method includes the steps that a first glass substrate ofa liquid-crystal-optics phased-array antenna serves as a public substrate, one side of the public substrate is coated with a conductive film to serve as a third electrode layer, a slant second glass substrate is arranged on the same side of the first glass substrate, and the side, close to the first glass substrate, of the second glass substrate is coated with a conductive film to serve as a fourth electrode layer; a liquid-crystal material is canned between the third electrode layer and the fourth electrode layer and serves as a second liquid-crystal layer; continuous voltage is loaded on thefourth electrode layer, and incident beams are subjected to continuous deflection controlling; disperse voltage is loaded on the first electrode layer of the liquid-crystal-optics phased-array antenna, and incident wave beams are subjected to large-angle disperse scanning; disperse voltage is finally loaded on the first electrode layer of the liquid-crystal-optics phased-array antenna, and incident wave beams are subjected to large-angle disperse scanning; continuous voltage is loaded on the fourth electrode layer, and incident beams are subjected to continuous deflection controlling.

Description

technical field [0001] The invention relates to a cascaded liquid crystal optical phased array antenna, forming and application methods, and belongs to the technical fields of satellite laser communication and laser radar. Background technique [0002] At present, the laser communication system researched at home and abroad is a point-to-point single-link data transmission system, which uses a mechanical catch-and-follow mechanism. Due to the long distance of the satellite laser communication link and the limited laser emission power, the divergence angle of the laser beam needs to be as close as possible to the diffraction limit. Limited by the divergence angle of the laser beam, the space laser communication system using a mechanical scanning mechanism can only realize point-to-point laser communication. Laser communication terminals using a mechanical scanning mechanism are large in size and weight, and it is difficult to meet the miniaturization and light weight require...
