An infrared spectrometer, which used a linear array of quantum grid infrared photodetectors (QGIP) as its spectral sensing elements, was developed. The detector material, provided an 8-14 μm broadband absorption medium for the spectrometer. A linear array of QGIPs of various geometries was utilized, for the simultaneous detection of multiple wavelengths, and thus the array formed a spectrometer. The results indicate that the spectral resolution of a QGIP can be controlled through doping level of the detector material.
