Abstract
A persistent image retroreflecting display that enables the formation of a real image in free space includes a first light source that generates a polarized light output; a retroreflector module adjacent a first side of the first light source; a quarter waveplate coupled to the retroreflector module and adjacent the first light source; and a reflective polarizer positioned between the first light source and a viewer of the display.
