Abstract


The light-induced rotation in recent years the technology has become a hot research topic in the laser physics . The use of optical tweezers to study the method of light - induced rotation has been widespread concern , its advantage is the capture of the optical tweezers to fine particles without mechanical contact and suspension functions to avoid the contact of the particles with the sample bottom surface or other particles . Light-induced rotation angle birefringent crystal particles to manipulate , this is an increase of three-dimensional optical tweezers particles based on the manipulation of the one-dimensional angular light-induced rotation , as a new kind of optical micro- manipulation techniques , on the micromanipulator application significance . The main topic is the study of light-induced rotation of the uniaxial crystal particles , as follows : First, the theory of light tweezers technology principle and the principle of rotation technique photoluminescence overview of optical tweezers with light-induced rotation technique development and research status quo , as well as light-induced rotation of several methods and applications , and further describes the application of optical tweezers and light-induced rotation technique in biology, medicine , and other fields . Second , from the incident beam ellipticity , three aspects of the uniaxial crystal radius of the particles and the thickness of the uniaxial crystal particles analysis of the impact of the uniaxial crystal particle rotation angular velocity , and numerical simulation of MATLAB program of the factors mentioned above and theoretical analysis and experimental measurements provide preliminary theoretical basis for the next step . Finally, optical tweezers experimental parameters of the apparatus to be set by experiment uniaxial crystal particles affect light-induced rotation of the factors were analyzed and a graph showing the relationship of the uniaxial crystal particles of different radii of its rotational angular velocity is given , and experimental graph is compared and theoretical simulation diagram , the analysis of the reasons of possible errors in the experiment .
