abstract = "We review new algorithms that have been presented by us lately1 for fast reconstruction and phase unwrapping of sample wave-fronts recorded using off-axis digital holographic imaging. These algorithms enable reconstruction and phase unwrapping of sample wave-fronts up to 16 times faster than the conventional Fourier-based reconstruction algorithm. The algorithms exploit the compression properties of holographic imaging for decreasing the calculation complexity required for extracting the sample wave-front from the recorded interferogram. Using the presented algorithms, we were able to reconstruct, for the first time, 1 Mega pixels off-axis interferograms in more than 30 frames per second using a standard single-core personal computer on a Matlab-Labview interface, without using a graphic processing-unit programming or parallel computing. This computational speedup is important for real-time visualization, calculation and data extraction for dynamic samples and processes that are evaluated using off-axis digital holography such as biological cell imaging and real-time nondestructive testing.",
