Kotzer T, Rosen J, Shamir J
Appl Opt
. 2010 Nov;
34(20):3883-95.
PMID: 21052211
We describe generalized projection procedures for the design of arbitrary filter functions for correlators. More specifically, serial and parallel implementations of projection-based algorithms are employed. The novelty of this procedure...

Baharav Y, Shamir J
Appl Opt
. 2010 Nov;
34(12):2102-10.
PMID: 21037756
We analyze and quantify the capabilities and limitations of a double-conjugate adaptive-optics system. In the proposed system the contribution of two turbulent layers is treated separately, with Rayleigh guide stars...

Silvera E, Kotzer T, Shamir J
Appl Opt
. 2010 Nov;
34(11):1891-900.
PMID: 21037736
Mutually orthogonal pattern distortions are handled by an adaptive optical recognition system. A double-channel system is presented that implements pattern recognition with rotation, scale, and shift invariance. The recognition process...

Appl Opt
. 2010 Nov;
34(5):846-53.
PMID: 21037604
Several dynamical aspects of the DuPont photopolymer film HRF-150-38 for holographic storage are described. We study temporal aspects of exposure, exposure time, processing situations, and storage effect. The quantities studied...

Appl Opt
. 2010 Oct;
34(1):108-13.
PMID: 20963089
A wave-front sensor based on pseudo-phase-conjugate interferometry is presented. We show that a pseudo-phase-conjugate interferometer is suitable for the measurement of phase distribution on a propagating wave. This new method...

Piestun R, Rosen J, Shamir J
Appl Opt
. 2010 Oct;
33(20):4398-405.
PMID: 20935801
The principle of representing continuous complex-valued functions by their decomposition into three positive-valued ones is proposed for the generation of complex reference functions for a joint transform correlator. Three basic...

Singher L, Shamir J
Appl Opt
. 2010 Sep;
33(7):1180-6.
PMID: 20862135
Recording holographic optical elements in planar waveguides with both interfering beams being guided modes has certain advantages. We show that such holograms can be efficiently recorded when only a small...

Appl Opt
. 2010 Sep;
32(25):4706-12.
PMID: 20830135
A differential equation satisfied by the diffraction integral as a function of the off-axis coordinate in the observation plane is derived and its solution is obtained by expansion in Chebyshev...

Shamir J, Crowe D, Beletic J
Appl Opt
. 2010 Sep;
32(24):4618-28.
PMID: 20830125
Optical wave-front propagation in a layered model for the atmosphere is analyzed by the use of diffraction theory, leading to a novel approach for utilizing artificial guide stars. Considering recent...

Appl Opt
. 2010 Sep;
32(23):4423-9.
PMID: 20830101
The collective genetic algorithm introduced here uses a weighted averaging process for each generation that enhances its convergence. Based on vector-matrix multiplication, this algorithm is well suited for implementation on...
