This project will develop a miniaturized shortwave infrared (SWIR) spectrometer that is based on quantum dot absorptive filter array, with the following characteristics: small form-factor for portability, robustness due to absence of expensive and fragile dispersive optics, and quick acquisition due to the multiplexed filter array from which any arbitrary spectrum can be detected without scanning and be deconvoluted using a sophisticated algorithm. The miniaturized quantum dot spectrometer can be used in environments where the form-factor of the spectrometer and fast acquisition capability is crucial, such as space applications.
