Abstract: Methods and systems for presensitizing film, including providing an assembly of heads comprising N left heads, a center head, and N right heads, each head being configured to effect a corresponding process P, on one or more regions of a film, activating the left heads and the center head sequentially over a first region of the film, in response to the head assembly moving from left to right with respect to the film, and activating the right heads and the center head sequentially over a second region of the film, in response to the head assembly moving from right to left with respect to the film.

Abstract: Methods and systems for presensitizing film, including presensitizing a first region of a film, where the first region is a first subset of an image region, presensitizing a second region of the film, where the second region is a second subset of the image region, and where the presensitizing the second region of the film is performed subsequently to the presensitizing the first region of the film.

Abstract: Methods and systems for presensitizing film, including causing a presensitization effect on a region of a film, the presensitization effect, as a function of time, exhibiting a presensitization effect peak after a peak time from an initiation of the presensitization effect, and exposing, after a delay time, substantially the same region of the film to a spectrum of information-containing electromagnetic radiation, the presensitization effect at the delay time being substantially equal to the presensitization effect peak.

Abstract: In accordance with teachings of the present invention, a device accomplishes the task of reducing or preventing reflections of the reference beam off a diffuser from striking the holographic recording material. First, the device absorbs a large percentage of the reference beam power so that portion of the reference beam never reaches the diffuser. Second, the device blocks the small amount of reference beam that is incident on the diffuser and reflects back toward the film. Thus, the proposed device operates as an absorber-blocker (AB) for the reference beam.
