Wave-Based Inversion & Imaging for the Optical Quadrature Microscope

Abstract

The Center for Subsurface Sensing & Imaging System's (CenSSIS) Optical Quadrature Microscope (OQM) is a narrow band visible light microscope capable of measuring both amplitude and phase of a scattered field. We develop a diffraction tomography, that is, wavebased, scattered field inversion and imaging algorithm, for reconstructing the refractive index of the scattering object.
