Multifocal interferometric synthetic aperture microscopy

We extend interferometric synthetic aperture microscopy (ISAM) to optical coherence tomography (OCT) data collected with multiple positions of the focal plane. Multifocal ISAM achieves spatially invariant resolution like ISAM by applying the solution of the inverse problem to the forward model for each channel. A general regularized solution eliminates artifacts that affect multibeam OCT while achieving better signal-to-noise ratio over the entire image than is possible with single-focus ISAM. We present detailed theory, computer simulation, experimental results and analysis.
