In the Robert B. Goergen Hall for Biomedical Engineering and Optics on the UofR Campus is a Colloquia lecture by Dr. P. Scott Carney titled Synthetic Optical Holography.

Abstract: Scattering scanning near-field optical microscopy (s-SNOM) provides resolution of 5-10 nm and is inherently phase-sensitive. It is also slow, the bottleneck being the determination of phase and amplitude at each pixel. Holography is an efficient, multiplex method of acquiring phase across a whole image. I report on the marriage of holography and s-SNOM, a new development that improves the speed of nanooptical imaging by orders of magnitude while simplifying the experiment. Moreover, synthetic optical holography is quite general. I will show the method applied to confocal imaging where it provides phase sensitive data that may be coherently post-processed.
