They are used to implement amplitude, phase and polarization masks. In order to optimize its performance, it is important to characterize it, which means determining its Jones matrix. Here we present a method which consists on performing several intensity measurements for each gray level. It is simple enough that can be quickly performed, but offers much better results than previous methods.engjournal articlehttp://dx.doi.org/10.1117/12.2597156https://www.spiedigitallibrary.orgopen access535Spatial light modulatorJones matrixPolarimetryOptical metrology.Óptica (Física)2209.19 Óptica Física
