  • Light beam controller
    Patent number: 4040722
    Abstract: An acousto optical diffraction cell, capable of passing polychromatic radiation and useful in a high speed, high intensity character generator. A monoclinic prism behaves like a parallel plate of glass when deenergized, and diffracts light under Bragg angle conditions over a useful spectral range when energized, thus ensuring a high I1/I0 ratio. The cell can be used as a very fast linear scan device, or it can be used as a multiple light beam modulator.
