摘要

Abstract

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 (

) values of

= 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 demonstrat

ion of speckle reduction in modern vectorial laser-based imaging.
