Abstract:
In a system for visual effects involving apparel worn by a person, a method for projecting light including visual information onto a surface of the apparel so as to be observable by a viewer, comprising:providing a polarized light projector;providing a reflective polarization-maintaining surface carried by the apparel,providing another surface adjacent the reflective polarization-maintaining surface,projecting polarized light comprising latent visual information along a light path onto the reflective polarization-maintaining surface of apparel and then by reflection from said reflective polarization-maintaining surface of the apparel further along the light path to the viewer;projecting polarized light comprising latent visual information onto another surface adjacent said reflective polarization-maintaining surface;providing an analyzer in the light path which intercepts light traveling along the light path before the light reaches the viewer, the analyzer being positioned no earlier along the light path than substantially at said reflective polarization-maintaining surface of apparel worn by the person; whereby the visual information is resolved and made perceptible to the viewer as appearing at the reflective polarization-maintaining surface of the apparel, and whereby light comprising the visual information striking the other surface and reflected by the other surface is not resolved so as to be observable by the viewer as the visual effect.
