Abstract

The image quality obtained from a hologram depends to a great extend on the concerned wavefronts correctness. Departures from the assumed ideal wavefront exact profile and geo metry perfection lead to a loss of image resolution and diffraction efficiency. The problem is analysed by recourse to a wavefront representation in terms of the spatial frequency spectrum. The effects derived from the imperfect optical quality of the holographic recording medium and eventually the supporting substrate are considered. The problem is ana-lysed, in particular, for the wedge phase error and the sinuosoidal perturbation. The obtained results permit to derive a tolerance range for wavefront defects and therefore the substrate quality requirements. Relevance of the analysis to different applications are briefly discussed.
