We present an analysis of the efficiency of phase diffractive elements displayed onto spatial light modulators as a function of the device modulation. We show uses and strategies to compensate for the efficiency reduction in the presence of modulation defects like coupled amplitude modulation or non ideal phase modulation.
The Jones matrix formalism has been applied to evaluate the response of an optical system when a non-uniform polarizing pupil is introduced. With this formalism we analyze and experimentally demonstrate the properties of a binary polarization pupil filter having two regions with two orthogonal linear polarization orientations. We first study the case when no analyzer is placed behind the pupil filter,...
