Abstract:

Two digital computer simulation techniques are presented for use in evaluating the performance of mosaic patterned, photoconductive sensorelectroluminescent output, image conversion panels. One simulation technique is used for rapid calculation of output light for continuous input radiation levels varying over six orders of magnitude with the simulated panel operated at up to five different applied drive frequencies at each of five drive voltages. The second simulation technique evaluates the output brightness of the panel when operated at one frequency and voltage, but exposed to input radiation of chosen peak intensity and a square wave time profile. These computer simulations were used to evaluate combinations of available electroluminescent EL materials and near-infrared sensitive thin film photoconductors. Combinations such as PbS photoconductor with thin film ZnSMn EL lamps, CdSe photoconductor with thin film ZnSMn EL lamps, and CdSe photoconductor with thick film ZnSCu, Cl EL lamps were investigated.
