1. IntroductionHolography is an optical tool widely used for imaging microscopic objects in a wide range of applications and research disciplines [1,2,3,4,5,6,7]. In 1948, Dennis Gabor introduced a novel microscope that utilized the interference between the diffracted wavefront from microscopic objects and the illumination wavefront [8].

We present an optimal configuration for Stokes polarimeters based on liquid crystal variable retarders, with the minimum number of measurements. Due to the inherent variations of the director orientation of the liquid crystal molecules, we propose a configuration that minimizes the sensibility of the polarimeter to fast-axis variations.
