The temperature variations of several dielectric and optical parameters of KD2PO4 in the paraelectric phase above the Curie point are experimentally determined using an electron-beam-addressing technique. The results correlate well with the Curie-Weiss and electro-optical theories and the results of other researchers. The effects of these parameters on the performance of a KD2PO4 light valve are discussed and experimental image qualities are evaluated. The existence of domains in clamped plates and an unexplained hysteresis in the transition temperature are also reported.
