“…Recently there has been growing interest in the use of Synthetic Aperture (SA) methods in order to increase the effective aperture of the recording CCD [38][39][40][41][42][43][44]. This in turn may allow one to generate a reconstructed image with a higher resolution [39], although we do not demonstrate this effect in this paper, and also to generate reconstructions showing a much greater range of perspective in the third dimension.…”

The application of digital holography as a viable solution to 3D capture and display technology is examined. A review of the current state of the field is presented in which some of the major challenges involved in a digital holographic solution are highlighted. These challenges include (i) the removal of the DC and conjugate image terms, which are features of the holographic recording process, (ii) the reduction of speckle noise, a characteristic of a coherent imaging process, (iii) increasing the angular range of perspective of digital holograms (iv) and replaying captured and/or processed digital holograms using spatial light modulators. Each of these challenges are examined theoretically and several solutions are put forward. Experimental results are presented that demonstrate the validity of the theoretical solutions.

“…Thus, super resolution in digital holography has been also achieved by combining angular multiplexing using tilted illumination with coherence multiplexing [54]. The resulting approach not only improves the spatial resolution of the imaged object but also can be performed in a single illumination step.…”

Abstract. Optical super resolution is one of the most applicable as well as scientifically exciting field of optics dealing with imaging and aiming to improve the spatial resolvable capabilities of any imaging system (digital or ophthalmic) without modifying the optical parameters of the imaging lenses or the geometry of the detection array. Recent developments in nanotechnological fabrication capabilities open new doors of possibilities in fulfilling modified and improved super resolving configurations.Fundamental concepts for obtaining super resolved imaging are related with time, angular, wavelength, polarization and gray levels multiplexing. The state of the art in the field of optical super resolution is reviewed while showing its relation with nanophotonics.

“…As a result, the corresponding reconstructed images are band-limited in the frequency domain. Therefore the improvement of the resolution in digital holography is the main research focus [7][8][9][10][11][12][13][14][15][16][17][18].…”
