Several new materials have electrooptical coefficients that are high in comparison with that of lithium niobate (31 x 10-12 m/V). These new materials are SrxBai,Nb206 (SBN:100x); Sr Ba 1 K1 Na Nb206 (BSKNN); and polymeric, ultrathin films. For SBN:60, SBN:75, and BSKNN, electrooptical coefficients of 400 x 10- m7 V, 1400 X 10 m/V, and 150 x 10-12 m/V, respectively, have been reported.' In this paper, we review the theory of light-steering machines and predict the theoretical performance of these systems using these new electrooptical materials. We include new, innovative methods for increasing the resolution of these systems. In addressing problems in fabricating the crystals, we discuss crystal properties that must be controlled if the development of a practical crystal streak camera is to be successful. Finally, we present our experimental results from a laboratory-built light deflector using SBN:60.
