光束变换、输出<a href="http://display.oecr.com" target="_blank" class="relatedlink">显示</a>等诸多应用领域。液晶空间光调制器(SLM)以制作简单，价格低，耗能<br /> 低，易控制，易制成二维器件，且易构成并行光学信息处理器件等优点，倍受国内外研究<br /> 学者的关注。液晶空间光调制器又称光学快门阵列(OSAs) ,它将液晶层作为光调制<a href="http://material.oecr.com" target="_blank" class="relatedlink">材料</a>,<br /> 液晶层采用向列型液晶的混合场效应工作模式，在晶层上各区域施加不同的电场,可以引起<br /> 液晶分子排列方向和位置的变化,从而导致其光学性质的变化,实现对光信号的调制。本文<br /> 简要介绍了Holoeye的液晶空间光调制器，并列举其目前在光镊技术、螺旋位相相衬成像、<br /> 飞秒脉冲整形、自适应光学、光学投影等方面的应用。<br /> Holoeye的空间光调制器主要是基于透射或反射类型的液晶微显示技术，通过液晶分子<br /> 的旋光偏振性和双折射性来实现入射光束的波面振幅和相位的调制（如图1），可作为动态<br /> 光学元件，实时地调制光强和相位的空间分布。Holoeye SLM系列<a href="http://b.oecr.com/sell" target="_blank" class="relatedlink">产品</a>一般可分为相位<br /> 型、振幅型和振幅相位复合型。纯相位型调制范围都可达2π以上，振幅型对比度典型值为<br /> 2500:1，LC-R 1080可达10000:1。Holoeye SLM系列产品分辨率高，像素单元小，填充因<br /> 子高，衍射效率高，这样，实际应用中可获得高精度的波前控制。同时，帧频可达到<br /> 180Hz，有利于实时控制。Holoeye还提供了良好的<a href="http://opticaldesign.oecr.com" target="_blank" class="relatedlink">软件</a>控制界面，通过灰度图象控制SLM面<br /> 板像素单元对应的相位或振幅。目前，Holoeye的空间光调制器已在许多领域得到应用，下<br /> 面仅作一些简单的介绍。<br /> 图1 相位调制特性<a href="http://opticaltest.oecr.com" target="_blank"

class="relatedlink">物理</a>等领域中具有极其重要的作用，光镊本身也不断发<br /> 展并产生许多衍生光镊技术。利用全息元件或空间光调制器（SLM）所形成的全息光镊，在<br /> 多粒子操控方面的优势，为光镊技术走向实用化、规模工业生产打开了新局面，是目前光<br /> 镊家族极具活力的成员。<br /> 利用空间光调制器，可以灵活地实现光束的变换，获得所需的阱域分布。所谓阱域，<br /> 就是具有高梯度光强分布的区域，该区域可形成对微粒的三维束缚（如图2）。Andreas.H<br /> 等的实验装置中1），采用了Holoeye HEO 1080P II SLM，其分辨率为1920×1080，像<br /> 元大小8um。该实验中，为解决一般光镊系统高数值孔径物镜带来的短工作距离问题，设<br /> 计出Twin双光束技术，即另一部分光通过载波片的反射，形成与原会聚光对应的反向会聚<br /> 光。这样，可以减小散射光的影响，提高轴向作用力，在低数值孔径物镜下也可形成光</td></tr></table> <div class="pattl"> <ignore_js_op> <dl class="tattl attm"> <dt></dt> <dd> <p class="mbn"> <a

Gaussian光束，由于Laguerre-Gaussian具有轨道角动量，可以实现对微粒的旋转操<br /> 控，该研究引起了广泛的兴趣4）。<br /> 图2 Twin光阱全息光镊装置<br /> microscope objective=显微物镜 Object plane=物平面<br /> 螺旋位相相衬成像<br /> 在光学显微镜中，暗场或相衬方法常被用来提高物体成像的对比度。实质上，这些方<br /> 法都可看作是傅立叶平面上的光学滤波。类似于微分干涉相差显微技术，螺旋位相相衬法<br /> 也是利用对相移的敏感性来提高成像的清晰度，特别是边缘。由于光束的对称性，还可以<br /> 对各向均匀介质物体成像进行对比增强。并且，较传统相差显微成像，边缘对比度要提高<br /> 几个量级。如图3，Severin.F等采用了Holoeye 3000反射型SLM，分辨率1920×<br /> 1080，像元大小10um。通过它产生闪耀光栅执行滤波处理5)。这里，进行螺旋相位滤波<br /> 的全息光栅，中心有一个分叉，对应于位相不连续奇点。<br /> 图3 螺旋位相光束在成像中用于提高边缘对比度的实验装置<br /> Laser diode=激光二极管，Sample

滤波实现。图5是脉冲整形的基本装置6)，它是由衍射光栅、透镜和脉冲整形模板组成的4f<br /> 系统。超短激光脉冲照射到光栅和透镜上被色散成各个光频成份。在两透镜的中间位置上<br /> 插入一块空间模式的模板或可编程的空间光调制器，目的是调制空间色散的各光频成份的<br /> 振幅和位相遥，光栅和透镜看作是零色散脉冲压缩结构。超短脉冲中的各光频成份由第一<br /> 个衍射光栅角色散，然后在第一个透镜的焦平面聚焦成一个小的、衍射有限的光斑。这里<br /> 的各光频成份在一维方向上空间分离，在光栅上从不同角度散开，在第一个透镜的后焦平<br /> 面上进行了空间分离，第一个透镜实现了一次傅里叶变换。第二个透镜和光栅把这些分离<br /> 的所有频率成份重新组合，这样就得到了一个整形输出脉冲，这个输出脉冲的形状由光谱<br /> 面上模板的模式给出。<br /> 这里，E.Frumker 等只使用了一个透镜和光栅进行脉冲整形。其中，SLM 为Holoeye<br /> HEO 1080P，承受功率密度可大于2W/cm2。在制冷的状态下，可进一步提高光功率。<br /> 图5 飞秒脉冲整形实验光路图<br /> FL=聚焦透镜，M1,M2=反射镜，G=光栅，SM=扫描镜，L1,L2=透镜<br /> 自适应光学<br /> 自适应光学技术，是一种能够实时校正光学系统随机误差并使系统始终保持良好工作<br /> 性能的新技术，早期在天文观测中是用来修复大气湍流等因素对光波波前的扭曲，通过动<br /> 态地对波前误差的实时探测-控制-校正，来改善成像质量。目前，在眼底视网膜成像、大<br /> 视场显微成像等方面也得到应用。自适应光学系统中，关键部件是哈特曼波前传感器与变<br /> 形镜7)或空间光调制器（图6）。<br /> 另外，SLM还可用来模拟大气扰动，为实验室里研究大气中光学成像提供有力支持<br /> 8)。<br /> 图6 光波前闭环控制示意图</td></tr></table> </div> <div id="comment_615994" class="cm"> </div> <div id="post_rate_div_615994"></div>
