Digital Holography at Restricted Conditions and Photon Counting Approach

Digital holography and interferometry provide high quality solutions to a wide range of applications. While holography enables recording and recreation of amplitude and phase information of complex three-dimensional wave fronts, interferometry enables the analysis of static and dynamic changes in these wave fronts. Recording of digital holograms is usually performed by array photo-detectors like CCD cameras and the object is reconstructed numerically. Although very efficient, digital recording (i.e. replacing photo-emulsions with CCD sensors) has introduced some limitations such as lower resolutions and limited dynamic range.
