Operation of a conducting PRIZ

The construction and operation of a PRIZ spatial light modulator is reported using semi-transparent electrodes and no insulating layers. Qualitative observations of the dynamic properties of such conducting devices are found to be similar to those reported in the Soviet literature with several exceptions. The devices demonstrated dynamic detection, memory, and oscillatory instability as well as the typical directional filtering and dc suppression of the standard PRIZ which uses insulating layers. This is the first report of a non-Soviet built device of this type.
