摘要
数字微镜器件(DMD)可以对反射后的光线进行分束,再经过透镜聚光后,能够形成点光源阵列,其中点的大小、间距都可以很方便地控制。相较于传统的微光学器件,DMD 具有不可比拟的柔性,而且成本很低。利用DMD 构建的数字并行光源可以用于并行共焦显微探测,实验搭建了一条适应于目前测量环境的光路,对比了周期不等的点光源阵列后,得到了在同时满足DMD 和CCD 的像素要求的前提下,阵列周期越小越能提高测量纵向分辨力的结论。
Abstract
The light could be split into lots of beams with Digital Micromirror (DMD), and focused by convex lens. Then,a point light source array will be formed, in which the size of point and the space between points can be controlled conveniently. The DMD is more flexible and cheaper than the traditional micro optic elements. With a digital parallel light source constructed with DMD used in parallel confocal microscopy detecting, an optical path is designed for current measurement environment. The experiment result indicates that the axial resolution could be improved with smaller period of point light source array, and the conclusion is based on the pixels of array meeting the needs of DMD and CCD.
