| Abstract: | Because the director of nematic liquid crystal can be controlled by the external electric field and the PDLC films can modulate light through a controllable scattering effect,the diffractive light intensity of PDLC grating can also be modulated by electric field.According to optical theories and through many experiments,now we can obtain ideal PDLC holographic gratings utilizing special recipe and technique.A novel optical switching can be produced by the superposition of such PDLC gratings with different spatial frequencies. |
