Claim:
A system for recording a hologram in a holographic recording material, the holographic recording material having at least a portion including a first surface and a second surface, the system comprising: a diffuser disposed adjacent to the second surface whereby an object beam directed at the second surface can pass through the diffuser prior to contacting the holographic recording material; and an absorber-blocker disposed between the second surface and the diffuser to prevent at least a portion of a reference beam directed at the first surface from impinging on the diffuser, the absorber-blocker including: a plurality of absorber-blocker material elements wherein at least one of the plurality of absorber-blocker material elements is a thin layer of material having a first absorber-blocker surface and a second absorber-blocker surface, and wherein the first absorber-blocker surface and the second absorber-blocker surface are in respective planes that are substantially parallel to a plane defined by the diffuser.
