Abstract:

A development program is described in which the feasibility of mosaic ELPC image conversion panels sensitive to UV, near IR, X-rays, and visible light was studied. Thin Film photoconductors are electroded in a regular array with unit cells 0.020 inches on centers. These arrays are connected to opaque electrode arrays forming the back pads of an electroluminescent EL lamp array through the use of microglass spacer sheets. Both thick film EL and thin film TFEL lamp arrays were prepared and studied. The combinations of materials used were prepared in test sample form, electrically and optically parameterized, and then computer simulations were performed to determine the range of parameters needed for a successful assembly. The computer models simulate the transient or steady state optical stimulation of ELPC cells with simple sinusoidal power applied or more complicated wave-forms. All computer programs used are documented.
