Review of Twin Reduction and Twin Removal Techniques in Holography

  title={Review of Twin Reduction and Twin Removal Techniques in Holography},
  author={Bryan M. Hennelly and Damien P. Kelly and Nitesh Pandey and David S. Monaghan},
In this paper we review the major contributions over the past sixty years to the subject of twin reduction and twin removal in holography. We show that this collective work may be broken down into a number of categories including the well known techniques of off-axis holography and phase retrieval. 
Twin image elimination in digital holography by combination of Fourier transformations
We present a new technique for removing twin image in in-line digital Fourier holography using a combination of Fourier transformations. Instead of recording only a Fourier transform hologram of the
Twin suppression in digital holography by means of speckle reduction.
A method for numerically removing the twin image in on-axis digital holography, based on multiple digital holograms, is discussed and experimental results presented that validate this model.
In-line hologram segmentation for volumetric samples.
The introduced hologram segmentation algorithm exploits the special inner structure of the in-line holograms and applies only the estimated supports and reconstruction distances of the corresponding objects as parameters to provide a good estimate about the contribution of the particular objects to the original hologram quickly.
Double-sideband filter for digital holography
Nowadays, digital holographic systems are based on two main optical schemes: off-axis (OA) and inline (IL) holographic systems. In OA set-ups, the reference and the object beams present a relative
Efficient Reconstruction of Holographic Lens-Free Images by Sparse Phase Recovery
This paper presents a computationally efficient technique to reconstruct holographic lens-free images based on sparsity, which improves image quality over existing techniques, allows for the possibility of reconstructing images over a 3D volume of focal-depths simultaneously from a single recorded hologram, and provides a robust estimate of the missing phase information in the hologram.
Quantitative phase imaging of low-cost digital in-line holography in comparison with off-axis digital holographic microscopy
QPI capability of LED-based digital inline holographic microscopy (LDHM) in comparison with the conventional off-axis DHM is discussed and the results of phase objects using both the methods are studied.
Wavefront holoscopy: application of digital in-line holography for the inspection of engraved marks in progressive addition lenses
An extremely simple optical device (named as wavefront holoscope) is presented for visualization and characterization of permanent marks in PAL based on digital in-line holography and experimental results are presented showing the applicability of the proposed method as a new ophthalmic instrument.
Lens-free digital in-line holographic imaging for wide field-of-view, high-resolution and real-time monitoring of complex microscopic objects
A high-throughput LHM system that is able to resolve 1.23μm-thin lines on a standard USAF 1951 test target with 1.67μm pixels at the full field-of-view, based on a unique multiwavelength iterative-phase-retrieval method.
Lens-free holographic imaging of microscopic objects using photonic structures and CMOS imagers
Current techniques to capture images of microscopic objects often rely on conventional microscopes, which are typically lens-based, resulting in bulky systems. While providing high spatial


Phase retrieval and twin-image elimination for in-line Fresnel holograms
Fourier phase-retrieval algorithms are modified and applied to in-line holography, where phase is lost during the hologram recording process and the rate of convergence is enhanced.

Properly phased combinations of images reconstructed from holograms recorded at several wave numbers suppress interobject multiple scattering, self-interference, and the troublesome holographic twin
Solution to the twin image problem in holography.
This work shows a universal method of reconstructing a hologram completely free of twin-image disturbances while no assumptions about absorbing or phase shifting properties of the object need to be imposed.
Single-Sideband Holography*
In making in-line holograms of amplitude objects with a strong background, the single-sideband technique can be used to improve the quality of the reconstruction. The main advantage of this method is
Twin-image noise reduction by phase retrieval in in-line digital holography
Methods to improve numerically the reconstructed images by twin-image reduction are described, which are of great importance in in-line holography where spatial elimination of the twin- image cannot be carried out as in off-axis holographY.
Twin-image elimination experiments for three-dimensional images in optical scanning holography.
An experimental verification of the proposed twin-image elimination technique by optical acquisition of the two holograms and subsequent reconstruction of the complex hologram digitally is reported, and three-dimensional image reconstruction without twin- image noise is demonstrated.
On the absence of phase-recording or `twin-image' separation problems in `Gabor' (in-line) holography
In contrast with a general belief which followed Gabor's wavefront-reconstruction imaging work in 1948, the original Gabor `in-line' hologram recording scheme is shown to produce perfectly separable
