Illinois iOptics Lecture 3: A tissue scattering-phase theorem
17 May 2010 | | Contributor(s):: Gabriel Popescu
We have derived two mathematical relationships between quantitative phase images of thin tissue slices and the scattering parameters of the bulk, i.e. scattering mean free path, ls, and anisotropy factor, g. The ls turns out to be inversely proportional to the mean-squared phase shift and g is...

Illinois iOptics Lecture 1: Super Accuracy and Super-Resolution of Molecular Motors and Ion Channels
16 Apr 2010 | | Contributor(s):: Paul R Selvin
The standard diffraction limit of light is about 250 nm, meaning that you cannot "resolve" objects closer than this distance. Despite this, we have come up with a method to measure individual biomolecules with 1.5 nm spatial localization in x-y plane and 1-500 msec temporal resolution, using a...
