Abstract:We present the investigation which was conducted to improve the spatial and temporal performances of a deflecting system for display addressing. In a first part we describe the operation principle used to increase the optical deflection angle of an acousto-optic deflector. We show that it is possible to obtain an angular amplification simply by using a grating at grazing incidence angle ; the diffraction is then close to 90°. Experimental tests made with a 1200gr/mm grating have shown that an amplification of … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
