Abstract :
A new concept for infrared imaging using a pixelless photon frequency up-conversion device together with a CCD array is presented. The concept is applicable to wavelengths longer than the CCD response range (longer than about 1.1 μm). Preliminary imaging results using a quantum well infrared photodetector integrated with a light emitting diode are also presented
