Optical Field Reconstruction Using Phase-Space Tomography

Abstract

Measurement of light transport in a random, multiple scattering medium can provide details about the spatial structure of inhomogeneities within the medium. Progress made includes construction of a new system for making measurements of the complex, two-point optical field correlation function for continuous-wave laser light after propagating through a random-dielectric medium, in particular polystyrene spheres in water. The new system is based on a Sagnac shearing interferometer, with a CCD camera and computer processor. Several important design issues, dealing with resolution and throughput were solved by use of optical design software. Quantitative agreement has been found between measurements and theory, providing new insights into the behavior of light as it travels in random media.
