Imaging of properties of coherent elastic light scattering from turbid biological media

Imaging with coherent, elastically-scattered light for visualisation of thick-tissue morphology in vivo, or of cells buried deep in a turbid medium, remains a major challenge. We adopt an alternative approach of imaging of properties of light scattering based on regarding cellular tissue as a spatially-varying refractive-index continuum which encodes scattered light. We propose new methodologies to infer tissue state and morphology indirectly based on phase delay, speckle, and angle-resolved scattering. We will break new ground in correlating the structure and function of in situ epithelial tissue and cells to light scattering enabling, e.g., the detection of mitosis and apoptosis in cells buried in thick, turbid media, and of cancers and precancers in vivo.
