Recently a technique called optical trapping has been developed, so that small particles, whose typiucal diameters are from sub micronmeters to a few micrometers, are manupilated. In this project, we develop basic techniques for arranging small paricles and study optical properties of these structures.In the experimental setup, we have developed a new type of illumination optical system, consists of a projection optical system for two dimentional patterns and interference fringe patterns. Multiple particle trapping can be done by the method of pattern projection. Two dimensional arrangement of many particle is performed and shifted and rotated.Some theoretical studies have also done. We have developed a new theory of optical trapping for non focused beam. The optimum relation in optical trapping force is found in the width of illumination area and the particle size.

最近，一种被称为光学捕获的技术被开发出来，这样，典型直径从亚微米到几微米的小颗粒就可以被操纵。在这个项目中，我们发展了排列小粒子的基本技术，并研究了这些结构的光学性质。在实验装置中，我们开发了一种新型的照明光学系统，该系统由二维投影光学系统和干涉条纹光学系统组成。多粒子捕获可以通过模式投影的方法来实现。许多粒子进行二维排列，并进行移动和旋转。一些理论研究也已经完成。我们提出了一种新的非聚焦光束的光捕获理论。光捕获力的最佳关系是光照区宽度和粒子尺寸。
