Multi-dimensional Imaging by Compressive Digital Holography Academic Article uri icon

abstract

  • Unlike standard imaging, digital holography allows an indirect way to capture the complex field amplitude of a wavefront originating from an object. This provides three-dimensional (3D) information on the object recorded in a single two-dimensional (2D) recording device. Currently, digital holography is captured using a semiconductor based device and often reconstructed using numerical means on a computer. This type of holography is referred to as Digital Holography (DH)|| 1]. Digital holography is used in many areas including 3D imaging, digital holographic microscopy, aberration correction, holographic interferometry, and object surface and tomographic imaging. During the last few years, holography was successfully combined with the rapidly growing signal acquisition-reconstruction scheme known as compressive sensing (CS)[2–5]. With introduction of CS, a theory that …
