This paper discusses advances in the fabrication, operation, and performance of the Itek PROM (Pockels readout optical modulator). Devices of high optical quality have been made and evaluated. Measurements of MTF and sensitivity under various conditions are presented. Stored images can be enhanced in contrast by a change in device voltage and the same method used to suppress the zero order in Fraunhofer diffraction patterns of such images. The results of this technique are demonstrated.
本文讨论了伊泰克普克尔斯读出光调制器（Itek PROM）在制造、操作和性能方面的进展。已制造并评估了具有高光学质量的器件。给出了在各种条件下的调制传递函数（MTF）和灵敏度的测量结果。通过改变器件电压，可以增强存储图像的对比度，并且该方法也用于抑制此类图像的夫琅禾费衍射图样中的零级衍射。展示了该技术的结果。
