Abstract
High spatial frequency optical noise in the form of intensity contrasting picture elements in the display of a projected light image on a bead-oriented image-enhancing filter is significantly reduced by interposing light-scattering material in the optical path between a source of the projected light image and the display in order to inhibit formation and interference of coherent light waves, and to mask the appearance of separate or discrete beaded apertures.
