摘要

The conversion of infrared images in multiple quantum well inrared photodetector (QWIP) structure into nonuniform distribution of the current driving a light-emitting diode(LED) is considered using an analytical model. The developed model of pixelless QWIP-LED imagers takes into account transport processes determining the device operation. The contrast transfer characteristic is dervied as a function of the number of quantum wells and the electron capture parameter. It is shown that the quality of the up-converted imaes is improved with increasing number of quantum wells. The pixel-less imaging devices under consideration can effectively convert long-wavelength infrared image into short-wavelength infrared or visible images.
