The memory storage capabilities of a conducting PRIZ spatial light modulator were quantified. Analysis shows a relationship between the storage capabilities of the device and operation of the device as a dynamic image selector. Conditions for optimizing these capabilities are established. This is the first time quantified values have been presented concerning either the storage or dynamic imaging capabilities. The AFIT PRIZs exhibited memory capability for up to one hour. The operating conditions that affect the devices ability to store information are read beam onoff status, external electric field onoff status, and write beam energy density. Two other effects were observed and reported. One is an effect referred to as background glow. This is the first report of the glow. The second is reintensification of the output image. Construction of operational American devices exhibiting dynamic image selection was accomplished for only the second time. Fabrication of these devices was accomplished using the technique developed by Shields in his construction of the first non-Soviet PRIZ device exhibiting dynamic image selection.
