| Abstract: | The concepts of stretched polymer dispersed liquid crystal(PDLC) films and scattering polarizer are introduced.The preparation process and the spectral analysis for polarization characteristic of sheared PDLC films are given.Experiment results show that for 550nm wavelength,most transmittance T∥~60%,minimum transmittance T⊥~10%,and degree of polarization P~70%,the effects are same no matter absorption polarizer front position or postposition.The experiment results are significant for other scattering polarizer. |
