Patent number: 7295356Abstract: An apodization system for achieving a substantially uniform intensity profile of a modulated reference beam on a holographic recording medium. The substantially uniform intensity profile serves to improve the quality of any and all recorded holograms. In high-density holographic storage, the apodization system reduces the required hologram extent while still, maintaining any fidelity constraints (power budget, imaging tolerances, error-rate, noise floor). Furthermore, in high-fidelity holographic storage, better control of the hologram recording parameters can be established. The improved control allows tighter specifications on the image quality to be achieved.Type: GrantFiled: January 31, 2002Date of Patent: November 13, 2007Assignee: InPhase Technologies, Inc.Inventor: Brian King
