Electro/acousto optic technology has been proposed for a number of advanced programs. A review of these developments and their maturity lead to the apparent conclusion that the primary application of electro/acousto optics may be in ultra-high speed matrix or Fourier multiplication. Their current use and maturity are not sufficient to compete with digital electronics in other areas. A significant amount of basic research is still required to achieve demonstrative results which lead to technology insertion.
