PMID: 20868161
In the context of x-ray lensless imaging, we present a recent approach for Fourier transform holography based on the use of extended references. Major advances shown here rely on a...

PMID: 20820308
We describe several results characterizing the Hubble Space Telescope from measured point spread functions by using phase-retrieval algorithms. The Cramer-Rao lower bounds show that point spread functions taken well out...

Appl Opt
. 2010 Sep;
32(10):1737-46.
PMID: 20820307
Phase-retrieval algorithms have been developed that handle a complicated optical system that requires multiple Fresnellike transforms to propagate from one end of the system to the other including the absorption...

Appl Opt
. 2010 Apr;
21(15):2758-69.
PMID: 20396114
Iterative algorithms for phase retrieval from intensity data are compared to gradient search methods. Both the problem of phase retrieval from two intensity measurements (in electron microscopy or wave front...

Appl Opt
. 2010 Mar;
18(16):2812-23.
PMID: 20212755
The concept of a programmable multipurpose computation module for residue arithmetic is introduced. A possible design for the module is also presented. The application of the computation module in mathematical...

Appl Opt
. 2010 Mar;
18(5):631-40.
PMID: 20208792
The requirements on and the performance of holographic Fourier transform lenses for a matched-filter optical processor are discussed. The holographic aberrations were analyzed using a ray-tracing computer program, and holographic...

. 2009 Sep;
12(11):858-60.
PMID: 19741895
We demonstrate that unspeckled images of coherently illuminated, diffuse objects can be formed from measurements of backscattered laser-speckle intensity. The theoretical basis for this imaging technique is outlined, and results...

. 2009 Aug;
3(1):27-9.
PMID: 19684685
We present a digital method for solving the phase-retrieval problem of optical-coherence theory: the reconstruction of a general object from the modulus of its Fourier transform. This technique should be...
