Technical applications of acoustoopic signal processing units

The authors consider the basic ideas of acoustooptic signal processing where an acoustooptic unit is used as a spatial modulator. The selection of applications is oriented for the purposes of the security technology. Some experimental results based upon mercurous halides are summarized. These experimentally verified bulk acoustooptic units have been applied as a part of a model of a spectrum analyzer and of a model of a correlator. The potential advantages of these materials were demonstrated.<
