The important features of the spectrometer are: 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. Different batches of quantum dots will be used as a unique filter and deposited on a solid substrate as an array. The filtered spectrum is recorded by the SWIR camera as an intensity profile and translated into a meaningful spectrum via reconstruction 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.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.nasa.gov\/directorates\/spacetech\/strg\/nstrf-2016\"><strong>Back to NSTRF 2016 Full List<\/strong><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Jason Yoo Massachusetts Institute of Technology The goal is to developing a miniaturized shortwave infrared (SWIR) spectrometer that is based on quantum dot absorptive filter array.
