10.1 Introduction

Optical imaging suffers from a drawback inherent to the process of recording: the recording media (either photographic film or a digital camera) captures only the intensity of the incident light, sacrificing the three-dimensional data in the process, which lies in the phase of the electric field. In 1948 Dennis Gabor invented a technique which circumvents the loss of phase by adding a reference field to the recorded object [1]. This technique is dubbed holography, where the interference patterns between the object and the reference field can be recorded. These interference fringes depend on the phase of the object, therefore maintaining this information. If we write the recorded object in terms of amplitude and phase, add a reference field and record the obtained intensity we have
