| 1 | Zwitterion-doped liquid crystal speckle reducers for immersive displays and vectorial imaging显示文摘Lasers possess many attractive features(e.g.,high brightness,narrow linewidth,well-defined polarization)that make them the ideal illumination source for many different scientific and technological endeavors relating to imaging and the display of high-resolution information.However,their high-level of coherence can result in the formation of noise,referred to as speckle,that can corrupt and degrade images.Here,we demonstrate a new electro-optic technology for combatting laser speckle using a chiral nematic liquid crystal(LC)dispersed with zwitterionic dopants.Results are presented that demonstrate when driven at the optimum electric field conditions,the speckle noise can be reduced by>90%resulting in speckle contrast(C)values of C=0.07,which is approaching that required to be imperceptible to the human eye.This LC technology is then showcased in an array of different display and imaging applications,including a demonstration of speckle reduction in modern vectorial laser-based imaging. | Yihan Jin Nathan P.Spiller Chao He Grahame Faulkner Martin J.Booth Steve J.Elston Stephen M.Morris | 2023 | Light(Science & Applications)2023，12，11： | 0 |
