ABSTRACT:
A plurality of quantum-grid infrared photodetector (QGIP) elements are concatenated to form a spectrometer. Each of the QGIP elements is adapted to detect light at a particular range of wavelengths. Additionally, each QGIP element is adapted to produce a photocurrent that is proportional to the amount of light detected at its respective range of wavelengths. This type of configuration permits spectrometry within a spectrum that spans the aggregate ranges of wavelengths of each QGIP element.
