In order to achieve high-precision, controllable rotation of uniaxial crystal particles, we studied the theory and found the various factors that had an effect on optical rotation of uniaxial crystal, such as: the reflection of light beam on the crystal plane, the laser power, the thickness and radius of the particle,the reflective index and transmission index of the light beam, the phase contrast between the ordinary and extraordinary rays and so on. Based on the above analysis, the theoretical model of optical rotation was reconstructed,moreover, the optical rotation of calcium carbonate and silica particles chosen as experimental material were simulated and calculated, and the rationality of our theoretical model was testified by comparing with previously experimental data. The results indicated that the theoretical model provided even more accurate and reasonable theoretical supports for the experiment and application of optical rotation of uniaxial crystal particle. Our studies had great directive significance to optical driven micro-mechanical motor design and the material selection of rotor.
