Abstract

Ellipsometers and polarimeters or the like to investigate analyte containing fluids applied to a substrate-stage having a multiplicity of nano-structures that project non-normal to a surface thereof, including dynamics of interaction therewith, to the end of evaluating and presenting at least partial Jones or Mueller Matricies corresponding to a multiplicity of locations over an imaged area.
