Abstract: An optical system providing a “living camo”, a color and form changing camouflage achieved from a substantially planar transparent base film substrate having a first side and a second side, with the first side having an optical surface composed of an array of optical micro-lenses, and with the second side having a colorized camouflage pattern, such that the lens array on the first side interacts with the colorized camouflage pattern on the second side to exhibit a color and or form change when viewed from the first side at differing angles, and a method of manufacture same.

Abstract: A thin film containing a lens array on at least a portion of the surface consisting of a multilayered transparent polymer substrate exhibiting good flexibility and superior thermo-mechanical resistance to tension, heat, and humidity conditions wherein the total thickness of the thin film is at least half the focal length of the lens array.
