Abstract
A thirty months European Space Agency project started in March 2008, whose overall purpose is to expand and assess the performance of broadband (11-15μm) quantum detectors for spectro-imaging applications: Dispersive Spectrometers and Fourier Transform Spectrometers. We present here the development approach and the progress status concerning the detector layer and read-out circuit. For Dispersive applications a 42K operating temperature is currently achieved, which can still be increased, to approach the 50K goal value. For FTS applications efficient broadband optical coupling is demonstrated.
