| Sumario: | 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 implemented from scratch. Results obtained for several aberrated wavefront measurements show the suitability of these devices in this particular application. Due to the well-known dynamic properties of LCoS, these devices allow for an easy choice of the parameters of the SH sensor, i.e. the selection of the suitable focal length and aperture of the microlenses of the array, which will definitely determine the dynamic range and the lateral resolution of the SH sensor. © 2010 SPIE. |
