Four bird images in different stages of flight are stored on same location on film. Rotating film causes individual images to appear, left to right. These are stored in polarization-sensitive polymer film using spatial light modulator to interweave microgratings with orientation unique to each of the 4 images in a “super-pixel”. A single superpixel is shown in the below image. Black and white images are sent to spatial light modulator, resulting in film images shown in yellow.
