Multifilter phase imaging with partially coherent light

Applied Optics, 2014
A novel quantitative phase imaging method is shown to estimate phase accurately over a wide range of length scales using Köhler illumination from an extended incoherent source. The method is based on estimating the longitudinal intensity derivative in the transport-of-intensity equation via convolution with multiple Savitzky-Golay differentiation ...

Design of diffractive axicons for partially coherent light

Optics Letters, 1998
We propose a novel method of designing diffractive axicons for use in spatially partially coherent illumination. The design procedure is based on the results obtained by the stationary-phase method. The technique leads to a coherence-dependent differential equation with appropriate boundary conditions for the axicon phase function.

Holographic aberration compensation with partially coherent light

Optics Letters, 1982
The aberration-compensation method of passing the conjugate beam from a hologram through the same optical system used in making the hologram is combined with broad source interferometer techniques to give, along with the aberration compensation, considerable noise reduction. As with conventional photography, the image is two dimensional.

Focusing of Partially Coherent Light

1996
The focusing of fully coherent waves has been studied extensively over a period of many years.1 However, much less work has been done on the focusing of partially coherent fields. In fact, no satisfactory theory covering this subject exists. In the present paper we introduce a simple model for the analysis of problems of this kind.

Intrinsic degrees of coherence of partially polarized light

SPIE Proceedings, 2006
We address the problem of defining degrees of coherence for partially polarized light. We discuss a new theoretical approach that introduces intrinsic degrees of coherence. These parameters make it possible to separate partial polarization and partial coherence and are measurable quantities.

Elementary functions: propagation of partially coherent light

Journal of the Optical Society of America A, 2009
The theory of propagation of partially coherent light is well known, but performing numerical calculations still presents a difficulty because of the dimensionality of the problem. We propose using a recently introduced method based on the use of elementary functions [Wald et al. Proc. SPIE6040, 59621G (2005)] to reduce the integrals to two dimensions.

Two-Point Resolution with Partially Coherent Light*

Journal of the Optical Society of America, 1967
The two-point resolution problem has been discussed previously using the Sparrow criterion. However, this masks the real changes of the image structure as the degree of coherence between the two points changes. The only measurable quantity is, of course, the separation between the two object points.

The Wigner Distribution Function of Partially Coherent Light

Optica Acta: International Journal of Optics, 1981
The concept of the Wigner distribution function is applied to stochastic signals, in particular to partially coherent light. Relations between the Wigner distribution function, the power spectrum and related subjects are formulated. Some inequalities for the Wigner distribution function are derived; one of these inequalities leads to the definition of ...

Thermodynamic Entropy of Partially Coherent Light Beams

Journal of the Physical Society of Japan, 1964
The thermodynamic entropy of partially coherent light beams, as shown by M. von Laue, is given by the sum of the entropy of the principal waves, which represent the given light beams and are statistically independent of each other. The principal waves and their intensities are respectively the eigenfunctions and eigenvalues of the mutual intensity ...

On the Partial Coherence Theory for Nonstationary Light

1996
We offer a tentative contribution to the solution of problems that involve the use of nonstationary fields, based on the idea that the light spectrum of a nonstationary source can be considered an ensemble of correlated monochromatic components. We then apply this idea, considering that a reciprocal correspondence exists for the coherence of light in ...
