摘要： A hologram recording assembly includes a transparent, absorbent member supported on a substrate. The transparent member is positioned to be directly incident to an exposure beam. The transparent member is out of moisture equilibrium during an exposure time. Consequently, the transparent member increases or decreases in thickness depending on a moisture difference between it and the environment. As the thickness changes, a phase shift in the light reflections within the recording assembly blurs spurious holograms while leaving the desired hologram intact.

摘要： The systems of the invention form improved reflection and transmission holograms utilizing two beams and eliminating all of the higher energy spurious holographic recordings that are caused by reflections of rays from the outer surfaces of the cover plates. The systems provide movement of the cover plate or movement of the substrate and recording medium during the recording period to prevent formation of the spurious recordings. In some arrangements of the invention, global phase shifters are utilized to maintain the phase of the primary rays forming the desired hologram at a high level.

摘要： A method for precisely controlling the overall average diffraction efficiency of a hologram including the steps of (a) providing a hologram layer that includes a hologram formed pursuant to hologram forming exposure and development, (b) coating the hologram layer with a photoresist layer, (c) masking the photoresist layer with a mask having opaque and transparent areas wherein the proportion of the opaque areas relative to the transparent areas is selected pursuant to the desired diffraction efficiency, the opaque and transparent areas being sufficiently small so as to have little noticeable effect when the resulting hologram is played back, (d) exposing the photoresist layer to actinic illumination through the mask transparent areas, (e) developing the photoresist layer to remove the photoresist in the areas illuminated by the actinic illumination to uncover the areas of the recording material corresponding to the transparent areas of the mask, (f) etching the recording material to remove the areas thereof that were uncovered by etching of the photoresist, and (g) removing the remaining photoresist. The formation of the hologram can be at an effective exposure in the saturated region of the efficiency vs. exposure curve wherein changes in efficiency as a function of parameter variation are small.
