Paper 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 degrees. Experimental tests made with a 1200 gr/mm grating have shown that an amplification of the deflection angle as high as 10 can be obtained. In a second part we introduce a complete set-up composed by the association of MEMS, Acousto-optic and grating. All those components are used to achieve a compact addressing system.
