| Abstract: | Shifts in the thickness and the refractive-index of holographic recording materials occur naturally, degrading the performance of volume holograms, and reflection-type holograms in particular. In this study, pre-compensated design formulae are derived to correct these effects in fabricating volume reflection holograms. The experimental results are highly consistent with the theory. This method is also applicable to other phase media when the associated film shrinkage and refractive-index shift data are experimentally determined. |
