Quantum Dot Spectrometer, Year 2
Project Description
The main objectives of this CIF are to develop a novel, ultra-compact instrument concept using QDS, qualify QDS through thermal vacuum and vibration tests, and then demonstrate a 20x20 array prototype between the range of 480 to 680 nm. However, the wavelength range can be expanded with more pixels, or a completely different range within 300 to 3000 nm can be achieved by selecting an appropriate set of QDs and detector. The end product of this task will be a preliminary prototype QDS integrated with a detector array, and spectral images produced by the system. As a follow-on effort the PI and team intend to apply to the Advanced Component Technologies program in 2017 to complete the proof-of-concept of the technology and reach a TRL of 3. After that, the team will apply to the Instrument Incubator Program to develop a breadboard and test it in relevant environment, reaching a TRL of 5. At that point, the QDS instrument will be ready to be proposed to Earth Science mission opportunities.
More »Anticipated Benefits
This second-year effort continues development of a novel, ultra-compact, low mass, and low-cost multispectral imager based on an innovative quantum dot array (QDA) concept. This innovative QDA, based on a recent patent by MIT, acts as an absorptive filter and replaces prisms, gratings, interference filters and other optical components currently used in spectrometers. The advantages of such a Quantum Dot Spectrometer (QDS) make it a suitable instrument for small satellite missions in Earth Science, Heliophysics and Planetary Science.
