【Abstract】 Holographic polymer dispersed liquid crystals(HPDLC)are a kind of novel photoelectronic information functional materials. It has the perfect characters including high diffraction efficiency, rapid response and easy manufacture. HPDLC devices are potentially useful for optical communication, panel display, information storage and integrated optics. Based on the study of the diffraction properties optimization of HPDLC,we have established the measurement system for electro_optical properties of the HPDLC device. The influence of different surfactants loading on the anchoring energy of liquid crystal have been explored, which was demonstrated to be a good way to decrease the operating voltage. The experimental results indicated that the index matching plays an important role in improving the contrast ratio of device. The response time was measured and the average response time of 100μs was obtained.更多还原
