Colloquia: Synthetic Optical Holography

Dr. P. Scott Carney, Institute of Optics

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.
