abstract = "We review new and efficient algorithms, lately presented by us, for rapid reconstruction of quantitative phase maps from off-axis digital interferograms. These algorithms improve the conventional Fourier-based algorithm by using the Fourier transforms and the phase unwrapping process more efficiently, and thus decrease the calculation complexity required for extracting the sample phase map from the recorded interferograms. Using the new algorithms, on a standard personal computer without using the graphic processing-unit programming or parallel computing, we were able to speed up the processing and reach frame rates of up to 45 frames per second for one megapixel off-axis interferograms. These capabilities allow real-time visualization, calculation and data extraction for dynamic samples and processes, inspected by off-axis digital holography. Specific applications include biological cell imaging without labeling and real-time nondestructive testing.",
