| Abstract: | Liquid Crystal Spatial Light Modulator is an important device in real - time optical information processing. This paper analyzes the optical modulation characteristics of LC - SLM and its present applications in the holographic field. Based on the principle of optoelectronie reconstruction of the computer - generated hologram using Liquid Crystal spatial modulator, a new method of realizing sensorimetor Holography is proposed. Firstly the array of unit synthetic holograms are computed and stored, and then this array of holograms are written into the SLM sequentially for real - time optoelectronic reconstruction so that the sensorimotor Holography could be implemented. The basic principle and method is analyzed and the corresponding experimental result is demonstrated. |
