Abstract

Digital holographic imaging has applications across multiple disciplines, including microscopy and remote imaging. In many situations phase errors arise due to the propagation medium (atmospheric turbulence or tissue, for example) or when stitching together a synthetic aperture (due to time-varying motions of the object, of the data collection array, or of the phase of the reference beam, for example), and the result is a blurred image. This paper reviews some of the phase-error correction algorithms that allow a diffraction-limited image to be reconstructed from the collected data.
