Characterization of a parallel aligned liquid crystal on silicon and its application on a Shack-Hartmann sensor

In this paper, the characterization and the optimization of a parallel aligned (PA) liquid crystal on silicon display (LCoS) has been conducted with the aim to apply it to the generation of a microlenses array in a Shack-Hartmann (SH) sensor. The entire sensor setup has been experimentally implement...
