Abstract
The optical and electrical switching characteristics of a lead zirconate titanate ferroelectric ceramic 'with Bi or La doping were studied for possible application in a high speed light valve array. Of particular interest were the requirements for coincident voltage selection and stable operation for at least 1010 switching cycles. Excitation aging was found to decrease the contrast achievable when the ceramic is used as an electrically controlled retarder. A more pronounced result of aging is a large increase in the degree of partial switching caused by half-select pulses. Such effects could be temporarily reversed by appropriate cycling to higher temperatures. Little variation in aging with different electrode materials was observed.
