Abstract:

This talk will describe new methods for achieving high-resolution 3D intensity and phase images in a commercial microscope, by computational approaches. We describe setups employing illumination-side and detection-side coding of angle (Fourier) space for capturing 4D phase-space (e.g. light field) and phase retrieval data sets with fast acquisition times. Experimentally, we achieve real-time 3D and phase imaging with digital aberration correction and mitigation of scattering effects. The result is a high-resolution image with a large field of view, approaching Gigapixel-scale space-bandwidth-time product. Such computational approaches to optical microscopy add significant new capabilities to commercial biological microscopes without significant hardware modification.
