Camouflage by Controllable Color Changes
Abstract
A practical camouflage system whose colors and color patterns can be continuously, controllably and reversibly varied on command would be of great tactical importance to mobile army units. In the study described a number of possible approaches were researched, an extensive literature search was carried out, and some laboratory investigations performed. From considerations of each of these approaches, the state-of-the-art in materials technology, and of the requirements of the program, a liquid crystal approach was deemed to have the best potential for demonstrating the feasibility of a variable camouflage system. By electrically varying the temperature of a cholesteric liquid crystal, the color is also varied. The concept has been demonstrated to be reversible, controllable and reproducible, even though the colors and color ranges obtained are not ideal.
