Imaging beyond the ballistic limit in coherence imaging using multiply scattered light.

Giacomelli MG, Wax A - Opt Express (2011)

Bottom Line: We present an imaging system based on low coherence interferometric detection of multiply scattered light for extended depth imaging into highly scattering media.By incorporating angle-resolved detection, coherence imaging with multiply scattered photons is shown to be both feasible and potentially superior to existing techniques for performing time-resolved measurements of scattered light.The resolution and imaging contrast are compared to those obtained with conventional OCT systems which chiefly detect singly scattered light.

ABSTRACT
We present an imaging system based on low coherence interferometric detection of multiply scattered light for extended depth imaging into highly scattering media. By incorporating angle-resolved detection, coherence imaging with multiply scattered photons is shown to be both feasible and potentially superior to existing techniques for performing time-resolved measurements of scattered light. Imaging is demonstrated through nearly 100 mean free paths of scattering phantom in a single-ended geometry. The resolution and imaging contrast are compared to those obtained with conventional OCT systems which chiefly detect singly scattered light.
