A scattering polarizer is created by subjecting a polymer dispersed liquid crystal film to tensile strain. The optomechanical properties of the film are investigated by simultaneously measuring the stress–strain and polarization dependent optical transmission characteristics. The correlation between transmittances of two orthogonal polarizations and the stress–strain curve reveals that the polymer orientation as well as the droplet shape anisotropy influences the liquid crystal alignment within the droplets. A Monte Carlo simulation based on the P. A. Lebwohl–G. Lasher [Phys. Rev. A 6, 426 (1972)] model is used to explain the subtle influence of polymer orientation on liquid crystal alignment. ©2003 American Institute of Physics.
