| 摘要 |
本发明系提供一种瞳孔位置侦测控制液晶之视轴调节系统，其包含：至少一曲面透镜，其分别连接一曲面棱镜，所述曲面透镜及曲面棱镜间，分别邻接一电致动单元；至少一瞳孔侦测单元，其系侦测至少一瞳孔位置；一感测单元，其系侦测一环境状态；藉之，本发明系透过分析瞳孔位置以界定其视轴，并藉由侦测一目标物与电致动单元间之距离或电致动单元之倾角值，藉以调整电致动单元之曲率半径，令通过曲面棱镜之光线与所述曲面棱镜之光轴呈平行，并同时校正曲面透镜之焦距，令使用者无论观察远方或近处，皆可透过电致动单元及曲面棱镜，使其双目之视轴皆与曲面棱镜之光轴呈平行，以降低使用者双目之疲劳，并可有效校正视力，藉以减低使用者因焦距变换而晕眩之发生概率，且可适用于各式场合，如：眺望、俯瞰、仰视、阅读或运动，使大幅提升本发明之便利性及适用性者。; at least one pupil detection unit for detecting at least one pupil position; and a sensor for detecting an environment state. The present invention define the visual axis by analyzing said pupil position, detect a distance between an object and the electric actuation or a dip of the electric actuation to adjust the curvature radius of the electric actuator, let light through said curved prism parallel the optical axis of it, and correct the focal length of the curved lens. Whatever a user observe near or far, said electric actuator and curved prism can make the visual axis parallel the optical axis of the curved prism so as to reduce eye fatigue, correct vision, and decrease the chance of dizziness caused by changing the focal length. It can also use in all kinds of situations such as overlooking, reading, exercising so as to upgrade the practicality and convenience. |
