The objective of this research is to realize the miro-motor whose size is in the order of micron, by using radiation-pressure generated by laser beam as the driving force. The motor (linear, rotational, or levitational) is driven by laser beam, without using mechanical or electrical means. In the research, the experiments on the driving of mirco particles was conducted. The driving force by the radiation pressure was also theoretically analyzed.The experiment of three-dimensional laser-beam manipulation of the particle was carried out. This particle correspondes to the moving part in the micro-motor. Effects of the material, size, shape and mass of the particle were measured. The driving method with evanescent field was proposed. It was found out that the driving using evanescent field was promising way. Optimal conditions for this driving were evaluated experimentally.The driving force made from evanescent field was examined theoretically by using a physical model. By comparing the results of the numerical simulations with the experimental results, validness of the model was examined. Through the simulation results, the optimal condition to effectively obtain the maximum driving force was derived.Utilizing laser trapping techniques to assemble micro-motor was also considered, and the feasibility was investigated experimentally.

这项研究的目的是通过使用激光束产生的辐射压力作为驱动力来实现其大小按微米顺序达到微米顺序的动作。电动机（线性，旋转或悬浮）由激光束驱动，而无需使用机械或电气方式。在研究中，进行了有关驱动mirco颗粒的实验。理论上还分析了辐射压力的驱动力。进行了对粒子的三维激光束操纵的实验。该粒子对应于微型运动中的移动部分。测量材料，大小，形状和质量的影响。提出了带有ivaneven田的驾驶方法。人们发现，使用Evanescent领域的驾驶是有希望的。通过实验评估了这种驾驶的最佳条件。通过使用物理模型，在理论上检查了逃生场制成的驱动力。通过将数值模拟的结果与实验结果进行比较，可以检查模型的有效性。通过仿真结果，还考虑了将激光捕获技术汇总到组装微型运动器的最佳条件，并通过实验研究了可行性。
