Abstract
Based on type-II InAs/GaSb superlattice photodiodes, the first report of a dual-colour infrared camera with excellent NETD values <30 mK for the shortwave channel with a cutoff wavelength of 4.0 mum and <17 mK for the longwave channel with 5.0 mum cutoff is presented. The bispectral system, which offers a simultaneous and pixel-registered detection of both colours, allows remote imaging of carbon dioxide.
