Abstract

Digital Speckle Pattern Interferometry is used to investigate and measure the transient and non-local refractive index change in a 32 μm-thick homeotropic sample of a methyl red-doped nematic liquid crystal E7 illuminated by an Argon-ion laser (λ = 514.5 nm). Changes in the birefringence are readily observed as changes in the transmittance and the interference pattern obtained from the He-Ne (λ = 632.8 nm) laser probe.
