Abstract

Methods and systems for forming holographic gratings are described herein. The methods and systems may decrease the amount of haze produced during exposure of a holographic recording medium. In some embodiments, the methods and systems include a holographic recording medium; a master hologram containing a grating; and a light source and moveable deflector configured to diffract light through the master hologram into the holographic medium to form a holographic interference pattern. The moveable deflector is configured to move in a direction parallel to the extending direction of the grating. Advantageously, moving the light in this direction allows the holographic interference pattern to remain stationary while there is a spatio-temporal displacement and cancellation of unwanted intensity nonuniformities.
