Artifact-Free Reconstruction from Off-Axis Digital Holograms Through Nonlinear Filtering

N. Pavillon, C.S. Seelamantula, M. Unser, C. Depeursinge

Proceedings of SPIE Photonics Europe 2010: Optics, Photonics and Digital Technologies for Multimedia Applications, Brussels, Kingdom of Belgium, April 12-15, 2010, vol. 7723, paper no. 77231U.


We present experimental investigation of a new reconstruction method for off-axis digital holographic microscopy (DHM). This method effectively suppresses the object auto-correlation, commonly called the zero-order term, from holographic measurements, thereby suppressing the artifacts generated by the intensities of the two beams employed for interference from complex wavefield reconstruction. The algorithm is based on non-linear filtering, and can be applied to standard DHM setups, with realistic recording conditions. We study the applicability of the technique under different experimental configurations, such as topographic images of microscopic specimens or speckle holograms.
