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 will report on the marriage of holography and s-SNOM, a new development that improves the speed of nano-optical imaging by orders of magnitude while simplifying the experiment.  Examples will be given of large-scale (megapixel) imaging of manufactured nanostructures, CVD-grown materials, and the capture of dynamics not before possible.



Prof Carney holds a BS in Engineering Physics from UIUC (1994), and a PhD in Physics from the University of Rochester (1999).  He joined the faculty of UIUC ECE in 2001.  He is a theorist with research interests in inverse problems, imaging, coherence theory and other branches of optical physics.
