Abstract: A method and apparatus for projecting scenes recorded upon additive color film. This film is typically configured having a filter screen portion overlaying an image carrying base. The filter screen may be formed as an array of parallel color stripes layed down in a repetitive sequence of colors such as red, green and blue. A diffraction grating of the transmission amplitude or phase variety is inserted in the optical path of a projector to cause zero and first order images of a recorded scene. The order images are mutually displaced so as to superimpose the film screen filter stripe images in a manner which substantially minimizes the visibility of the discrete color stripes at a display surface.

Abstract: This invention relates to light filters employing redox compounds that are substantially light-transmitting in their oxidized state and capable of forming a stable colored free radical upon the addition of electrons. The colored free radical formed in response to the flow of electric current renders the device light-absorbing. To restore the original lighttransmitting properties, the colored free radical may be readily reoxidized, for example, by reversing the direction of current flow.
Abstract translation: 本发明涉及采用氧化还原化合物的光过滤器，该氧化还原化合物在氧化状态下基本上是透光的，并且能够在加入电子时形成稳定着色的自由基。 响应于电流流动形成的着色自由基使得器件吸光。 为了恢复原始的透光特性，着色的自由基可以容易地再氧化，例如通过反转电流的方向。
