A technique is described for ensemble-averaging the light wave emerging from a turbid medium, enabling the recovery of optical information that is otherwise lost in a speckle pattern. The technique recovers both an amplitude and a phase function for a wave that has been corrupted by severe scattering, without the use of holography. With the phase estimated, an ensemble-averaged field is constructed that can be backprojected to form an image of the object obscured by the scattering medium… Expand

Comparison of field correlations in multiply scattered quasi-monochromatic light.
Results for 20-microm polymer spheres show that the latter correlation is consistently larger well into the multiple-scattering regime for wave-vector separations less than at least 50 mm(-1) and that the two correlations tend to merge in this scattering regime for larger wave- vector separations.

Optical determination of field angular correlation for transmission through three-dimensional turbid media
A method is presented for measuring the correlation between the optical fields scattered in different directions by an arbitrary three-dimensional turbid medium. The field angular correlationExpand
Spatial filtering for zero-order and twin-image elimination in digital off-axis holography.
Off-axis holograms recorded with a CCD camera are numerically reconstructed with a calculation of scalar diffraction in the Fresnel approximation. We show that the zero order of diffraction and theExpand
Inverse scattering with diffusing waves.
An analytic solution is derived from the singular value decomposition of the forward-scattering operator, which leads to explicit inversion formulas for the inverse scattering problem with diffusing waves. Expand

Inverse problem in optical diffusion tomography. I. Fourier-Laplace inversion formulas.
Inversion formulas based on the Fourier-Laplace transform are used to establish the existence and uniqueness of solutions to the inverse problem of reconstructing the absorption and diffusion coefficients of an inhomogeneous highly scattering medium probed by diffuse light. Expand


Coherent image synthesis from wave-front sensor measurements of a nonimaged laser speckle field: a laboratory demonstrations.
The design of the wave-front sensor is discussed, which can obtain the phase and amplitude of an optical field with a single intensity measurement, and a particular type of phase jump is pointed out that cannot be detected by the Shack-Hartmann sensor. Expand
Ensemble-averaged imaging through highly scattering media.
A method for imaging through highly scattering media is described that consists of forming a multiplicity of holograms and performing an extensive averaging process to form an ensemble-averaged wave front that can be backprojected to form a image of absorbers within or behind the scattering medium.

Shack Hartmann wave-front measurement with a large F-number plastic microlens array.

Time-gated ensemble-averaged imaging through highly scattering media.
A previously described ensemble-averaged imaging method is extended by its combination with holographically implemented time-gated imaging to extend the effectiveness of the ensemble-aversaged method by permitting imaging through thicker diffusers. Expand
