Active-subspace analysis of speckle-based particle measurements

Abstract

We consider laser speckle measurements of concentrations of particle suspensions in a medium when the refractive index n and the size parameter a of the particles are uncertain. Using active-subspace analysis, we quantify the sensitivity of speckle intensity measurements to parameter changes along general directions in the (n,a)-space.
