Paper Abstract

We report algorithms and laboratory practices that tell the full complex behavior of an SLM over its entire face, pixel by pixel, and put the information into a form that is useful to our filter optimization code. We add a quadrature component to the interferometry and image each pixel of the SLM. We analyze the fringes not at one value of drive and in an across-pixels dimension, but instead at each pixel in the drive dimension. We describe details of the method and given examples of spatially-variant filter SLM behavior. We provide examples of performance degradation when the filter's spatial variance has not been accommodated.
