对于诸如光学数据存储、激光印刷、头盔显示器等应用技术来说,激光束的角位置和光点尺寸是很重要的,传统的方法不得不用独立的元件分别控制聚焦和扫描,若将这些元件集合在一块,在一个生产步骤加工,将能降低这些器件的生产成本.洛斯阿拉莫斯国家实验室和新墨西哥州的卡内基—梅隆大学的一组科学家们已研制出一种可分别控制的并集成在一块LiTaO_3单晶上的电光透镜和扫描器.控制这个透镜组和扫描器元件能使极大数目分辨的光点落在离该器件任意距离的点处.这对于印刷和读写等应用来说是很重要
For applications such as optical data storage, laser printing, helmet displays and the like, the angular position and spot size of the laser beam are important. Conventional methods have to separately focus and scan with separate components. If these components are assembled in And processing in one production step will reduce the cost of manufacturing these devices.A team of scientists at Los Alamos National Laboratory and Carnegie-Mellon University in New Mexico have developed a separately controllable Electro-optic lenses and scanners integrated on a single LiTaO_3 single crystal. Controlling this lens set and scanner element allows a very large number of resolved light spots to be placed at arbitrary distances from the device, for applications such as printing and reading and writing It is very important
