Development of Digital Micro-Mirror Device Arrays for Use in Future Space Missions
PI
: Zoran Ninkov/Rochester Institute of Technology
Objectives and Key Challenges :
A technology is needed that allows selection of targets in a field of view that can be put into an imaging spectrometer for use in remote sensing and astronomyWe are looking to modify and develop COTS Digital Micro-mirror Devices (DMD) for this application
Significance of Work :Existing DMDs need to have their commercial windows replaced with windows appropriate for the scientific application desiredThe radiation hardness and scattering properties of the DMDs need to be investigated
Approach:Use available 0.7 XGA DMD devices to develop window-removal procedures and then replace delivered window with a hermetically sealed UV transmissive one (magnesium fluoride or HEM Sapphire)Test and evaluate such devices as well as Cinema DMDs (2018 x 1080)
Key Collaborators:Sally Heap, Manuel Quijada (NASA/GSFC)Massimo Robberto (STScI)Alan Raisanen (RIT)
Current Funded Period of Performance: May 2014 – May 2016
Recent Accomplishments:0.7 XGA DMDs ordered and delivered (Dec 2014)MgF2 and HEM Sapphire windows delivered (Jun 2015)DMD de-lidded at RIT characterized at GSFC (Jun 2015)Next MilestonesXGA DMD with Sapphire & MgF2 windows delivery (Sep 2015)Cinema DMD and electronics delivery (Sep 2015)Heavy Ion testing at Texas A&M (Aug 2015)Scattered-light and contrast measurements (Dec 2015)
Application:Any hyper-spectral imaging missionGalaxy Evolution Spectroscopic Explorer
