Abstract
We give a brief description of a freespace beam steering crossbar switch design using acousto-optic deflectors, and report the results of an experiment to accurately measure beam deflection time for the beam width required to support our design. A beam diameter of lmm to allow reasonable separation of 32 potential targets along an axis was steerable in 130 ns to 569 ns, depending on beam proximity to the piezoelectric transducer. All experimental components and instru-mentation used are commercially available.
