Noise reducing phase retrieval
Applied Optics, 2015In the context of imaging using the Hanbury Brown-Twiss effect, this paper describes a phase retrieval algorithm capable of producing high-quality images despite large amounts of noise in the coherence magnitude measurement data. Previously the problem was conceived as two distinct steps: coherence magnitude estimation, followed by image construction ...

The problem of reconstructing an object function from the modulus of its Fourier transform arises in many disciplines. Several algorithms have been proposed to solve this problem. One of the most successful of those algorithms is the iterative transform algorithm, but is has a disadvantage in that it stagnates before it reaches a solution in some cases.

2010 International Symposium on Optomechatronic Technologies, 2010
Imaging the internal structure of quasi-transparent three-dimensional (3D) objects is one of the most challenging tasks for optical systems. If the light propagates coherently through the volumetric object, then collection of phase projections from different angles and tomographic reconstruction are required.

Diversity selection for phase-diverse phase retrieval
Journal of the Optical Society of America A, 2003Wavefront-sensing performance is assessed for focus-diverse phase retrieval as the aberration spatial frequency and the diversity defocus are varied. The analysis includes analytical predictions for optimal diversity values corresponding to the recovery of a dominant spatial-frequency component in the pupil.

Phase-space interpretation of deterministic phase retrieval
Journal of the Optical Society of America A, 2004Deterministic phase retrieval is reinterpreted in terms of phase-space optics. A novel derivation of the transport-of-intensity equation is presented based on the Wigner distribution function and the ambiguity function. The phase retrieval problem is formulated as estimating the local first-order moment of the Wigner function from intensity information.

Phase retrieval by pinhole scanning
Optics Letters, 2011We describe a method where phase and amplitude of a wavefront are obtained by processing a sequence of pattern produced by the interference between the light transmitted by a scanning pinhole (which is sequentially shifted) and a reference pinhole. Simulations and experimental results are presented.

In this letter we construct frames consisting of 5d − 4 vectors that enable a both uniform and tractable recovery for the phase retrieval problem in ℂd.
