Digital holography super-resolution for accurate three dimensional reconstruction of particle holograms

Abstract : In-line digital holography is used in many fields to locate and size micro-or nano-objects spread in a volume. To reconstruct simple shaped objects, the optimal approach is to fit an imaging model to accurately estimate their position and their characteristic parameters. Increasing the accuracy of the reconstruction is a big issue in digital holography, particularly when the pixel is large or the signal-to-noise ratio is low. We suggest exploiting the information redundancy of videos to improve the reconstruction of the holograms by jointly estimating the position of the objects and the characteristic parameters. Using synthetic and experimental data we checked experimentally that this approach can improve the accuracy of the reconstruction by a factor more than the square root of the image number.
