Noise originating from the coherent nature of laser light is the scourge of digital holography, reducing the quality of holographic images below that of conventional photographs. Now, Pasquale Memmolo of ISASI-CNR and collaborators have practically eliminated such noise by using a two-stage algorithm that exhibited both qualitative and quantitative improvement over recently developed de-noising techniques. In particular, the algorithm reduced noise in background regions by 98 percent and in signal regions by 92 percent.
