The principle, simulation and realization of photon-forceps

摘要

This thesis analyzed the principle of photon-forceps and explained the effects that a laser beam acts on a transparent particle using the simple theory of radial optics. We also established a model of ray-trap which can catch particles easily and simulated a photon-forceps which is produced by a highly focused laser beam. And with computer we calculated the catching power of this forceps to the transparent tiny balls whose diameters are from 1 μ m to 10 μ m. In addition, to realize the photon-forceps we carry out a new focusing system. On the base of analyzing the value gotten in computing process, an improved forceps was achieved.
