W. Lu et al., APPLICATION OF GAAS GAALAS MULTIPLE-QUANTUM-WELL INFRARED DETECTOR ARRAY IN THE INFRARED IMAGING CAMERA/, International journal of infrared and millimeter waves, 15(1), 1994, pp. 137-144
A long-wavelength (lambda(p) = 7.7 mu m) infrared imaging camera that
uses a GaAs/GaAlAs multiple-quantum-well infrared photo-detector array
is presented. A good infrared image of a group of buildings and trees
is demonstrated.
