optical interferometry is being used as an efficient tool to analyse smooth surfaces for more than a century. although, due to introduction of novel computer assisted analyzing techniques and array detectors, like ccd, the speed and the precision of processing have been increased tremendously, but the main equation involved is not changed. the main equation is the intensity distribution in the ...

We provide the rigorous derivation of wave kinetic equation from cubic nonlinear Schrödinger (NLS) at timescale, under a particular scaling law that describes limiting process. This solves main conjecture in theory turbulence, i.e. systems. Our result is analog Lanford’s theorem on Boltzmann particle systems, where both cases one takes thermodynamic limit as size system diverges to infinity, an...
