Comparative studies of the noise power (Wiener) spectra of ultrafine grain Russian emulsions PFG-03 (PE-2) and IAE, of Western emulsions Agfa 8E75HD, Agfa 10E75, Ilford 737T and photothermoplastic materials for holography are performed. For the high-resolution materials PFG-03, IAE, Agfa 8E75HD used for recording both transmission and reflection holograms, the spectra are measured over both the forward and back hemisphere of scattering. The noise power spectrum measurements for the materials are compared with those for lenses what is important for technical applications. The results show that the scattering noise characteristics of the silver-halide emulsions are much better than those for the photothermoplastic material and, for the ultrafine emulsions, are even better than the lens noise performance.
