Abstract
A method for image intensification which avoids evacuated envelopes and utilizes a sandwiched layer of photoconductor and electroluminescent phosphor is described.The behavior of those components is approximated by empirical expressions which are used to derive the brightness gain feasible with such a device. This gain expression has been approximately substantiated. A working model of an image-intensifying panel was constructed which is able to intensify images by a factor of 2.
