| Abstract: | A wide-angle high-resolution beam steering system applying in space laser communication is designed. Liquid crystal spatial light modulator(LCSLM) to achieve narrow-angle beam steering is selected, and then multi-stages Wollaston prisms to reach angle-amplified is adopted. The beam steering principle of the LCSLM and the Wollaston prisms is introduced, and the simulation and analysis of the wide-angle high-resolution beam steering system is presented. The simulative results show that this beam steering system can achieve the angle range. It’s the first time to apply Wollaston prisms in wide-angle beam steering system domestically. |
