Abstract: The efficiency and bandwidth of an acoustic deflection cell are increased by using two transducers tuned to adjacent frequency bands and buffer member for causing the acoustic waves from the two transducers to propagate in different directions that are separately optimized. A frequency-sensitive switch connects an AC source to only one of the two transducers. The buffer member is designed to minimize or eliminate light deflection by spurious reflected acoustic components.
