Abstract

Retarder films exhibit polarization color by polarizer. We produced polarization colors with dual images using retarder films and polarizers. We calculated the polarization states by using Poincare sphere, and produced three types of polarization color devices: Polarization image with viewing angle dependence, polarization image with stacking order dependence, and polarization visual cryptography with stacking position dependence. In this paper, we show the experiment of polarization image with stacking order dependence.
