Abstract
A flexible optical surface, film or laminate using a non-rigid support substrate with a sufficient modulus of elasticity defining a controllable surface having a flat state so that repeatedly rolling-up the support substrate into a coiled state does not influence the flat state of the optical surface. The controllable surface can have one or more optical layers secured to the support substrate and use an optical pattern with predetermined optical characteristics to modulate incident light energy. One of the optical layers can be a reflective layer for forming a reflective controllable surface. The predetermined optical characteristic can modulate incident light energy to varying degrees such as by using a differential refraction or gain optical pattern according to the laws of optics.
