Paper Abstract

A static stereoscopic latent image (SSLI) created using photoaligned liquid crystal polymers is introduced. The image crosstalk and contrast are theoretically analyzed by adopting the Jones matrix method. The SSLI does not show any information for the naked eye, but displays a stereoscopic image using polarization spectacles. The image has three domains with even retardances but different optical axes directions with an angular separation of 45 deg. The two-eye view contrast is 0.6433 and the crosstalk is nearly zero, which agree with the theoretical results. This image is applicable to document security and information presentation, among others.
