Bispectral infrared (IR) cameras provide additional spectral information in contrast to common monospectral devices, which merely measure the integrated intensity of IR radiation. A bispectral IR camera has been manufactured from InAs/GaSb type-II superlattices. The two detector channels range from 3 - 4 µm and 4 - 5 µm, respectively. Thus, this camera is very sensitive to the spectral signature of carbon dioxide at approximately 4.3 µm and can be used for remote imaging of CO2.
