54‐1: Laser Speckle Reduction using Nanoparticle‐Embedded Liquid Crystals

Abstract

The ability to reduce laser speckle of a nanoparticle-embedded liquid crystal device with zero-power consumption is experimentally demonstrated. The scattering profile of nanoparticles smooths out the speckles from laser. The effects from tuning nanoparticle geometry and optical characteristics of liquid crystal host are theoretically evaluated.

“…Comparing the cells at the field-off state (Figure 2(a) vs. Figure 2(c)), the NP-doped LC cells shows a slight speckle reduction effect, which matches the phenomenon that was observed and reported in references [18,[25][26]. However, the laser speckle is reduced more significantly by inducing the electro-convection effect in LCs [27].…”
