Abstract
The optical strain characteristics of a reflective holographic-polymer disp
ersed liquid crystal are investigated. A spectral blueshift and induced pol
arization dependence are observed to occur with increasing strain. The spec
tral dependence on strain is explained by the Poisson contraction of the ma
terial and the polarization dependence is largely attributed to elongation
of liquid crystal droplets. The material has potential use as an optical st
rain gauge. (C) 2000 American Institute of Physics. [S0003-6951(00)01643-0]
