Multiplexed images using spatial light modulator to simulate motion

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.
