| Sumario: | In this work, we conduct a thoroughly comparison between different Stokes polarimeters based on Liquid Crystal Displays: polarimeters based on a single Twisted Nematic Liquid Crystal panel and on two Parallel Aligned Liquid Crystal panels. We carry out an optimization of the different polarimetric systems in order to reduce the noise propagation when measuring the polarization. In addition, we implement the three best optimized polarimeters. The experimental results are provided and discussed. We demonstrate that by performing an accurately optimization of a dynamic Stokes polarimeter based on a single Twisted Nematic Liquid Crystal panel, we achieve results close to those obtained by polarimeters based on two Parallel Aligned Liquid Crystal panels. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE). |
