Abstract / Description: 

This talk will describe new methods for achieving 3D and high-resolution phase information in commercial microscopes. Our setup involves replacing the illumination unit of the microscope with an LED array for computational illumination, enabling dark field, 3D and phase imaging in real-time. By rapidly scanning illumination angles using an LED array, we recover 3D light field and super-resolution information (beyond the diffraction limit of the objective), with embedded digital aberration correction. The result is a high-resolution gigapixel image of both phase and absorption information. Such computational approaches to optical microscopy add significant new capabilities to commercial microscopes, without significant cost or hardware modification.
