We report on the design of a particular holographic grating to be exploited for the stability control of an active optical holographic setup. The low-cost transmission grating made of alternating slices of pure polymer slices and pure nematic liquid crystal is used as a reference grating for the active feedback system that enables the interference patterns stabilization. The stability test of the interference pattern confirms the effectiveness of the proposed technique.

Abstract
We report on the design of a particular holographic grating to be exploited for the stability control of an active optical holographic setup. The low-cost transmission grating made of alternating slices of pure polymer slices and pure nematic liquid crystal is used as a reference grating for the active feedback system that enables the interference patterns stabilization. The stability test of the interference pattern confirms the effectiveness of the proposed technique.File in questo prodotto:
