Abstract: Accurate characterization of surfaces using cantilever-based optical beam deflection (OBD) systems is crucial for obtaining the sample’s “true” topography and its corresponding material ...

This core functionality of the project is implemented by Mohammad Sadegh Rasooli during his internship in Yahoo! labs and it was later modified in Columbia University. For more details, see the ...

Abstract: We investigated the effects of weak turbulent seawater on the propagation of orbital angular momentum (OAM) spiral modes carried by shift and deflection Bessel Gaussian beams. The analytic ...
