摘　　要：Standard GaAs/AlGaAs quantum well infrared photodetectors(QWIP)have been seriously considered as atechnological choice for the 3^(rd) generation of thermal imagers in the long wave infrared band(LWIR)for some time.Alternative technology like MCT(HgCdTe)was the technology choice of the 2^(nd) generation because of its high quantum efficiency.In the paper,measurements on the QWIP technology will be presented and a comparison with alternative technology will be done.Standard GaAs/AlGaAs quantum well infrared photodetectors （QWIP） have been seriously considered as atechnological choice for the 3rd generation of thermal imagers in the long wave infrared band （LWIR） for some time.
