These technologies include low-noise, high-speed, low-power and radiation hardened readout integrated circuit (ROIC) electronics; superconducting sensors; spectral detectors; polarization-sensitive detectors; radiation-hardened detectors; and micro-Kelvin and sub-Kelvin high sensitivity detectors that cover the spectrum from submillimeter wave (Far-IR) to X-ray.","exampleTechnologies":"Backshort Undergrid bolometer arrays, Mercury Cadmium Telluride and Strained Superlattice Arrays, charge coupled devices, sidecar readout integrated circuits, radiometric calibration and abnormality correction algorithms (e.g. non-uniformity)","hasChildren":false,"hasInteriorContent":true}],"startTrl":2,"currentTrl":5,"endTrl":5,"benefits":"The target application for our receiver will be laser detection and ranging. This includes Earth-based satellites, which use laser ranging to monitor atmospheric conditions and topographical features, or planetary mission that require laser altimeters for landing or topographical and atmospheric mapping. Select mission include: Aerosol-Cloud-Ecosystem (ACE), Doppler Wind Lidar for Surface Topology (LIST) and Geostationary Coastal Air Pollution Events (GEO-CAPE). NASA's existing systems, such as the Airborne cloud physics Lidar (CPL) and instruments for Wind and Raman Lidar, will also employ relevant receiver technology.
In addition to non-NASA laser ranging applications, the proposed detector would be useful for commercial technology related to optical communication, fluorescence lifetime imaging and medical imaging. The technology could be used as a low cost and compact receiver for high speed vehicle or object tracking. In addition, it would offer improved readout of scintillators for radiation detection and monitoring in health care and homeland security applications.","description":"In this effort, Radiation Monitoring Devices, Inc. (RMD) addresses NASA's request for sensitive, high quantum efficiency (QE) optical detectors for space- and ground-based light detection and ranging (Lidar) instruments. We propose to address this need by utilizing our latest designs in solid state photodetectors, and providing optimal receiver solutions needed for NASA's ongoing and future science missions. The solid state photodetectors that will be evaluated for this program will include RMD's large-area, high-gain proportional mode avalanche photodiodes (APD). The focus will be on modification of RMD's existing structure to improve responsivity and bandwidth in the blue and ultra-violet (UV) region of the spectrum. Preliminary studies have shown that UV responsivity and bandwidth of our large area detectors can be increased through the application of a modified surface layer using a well-established processing method. The proposed receiver technology readiness level (TRL) is estimated at 2. The Phase I effort will utilize experimental and theoretical studies to confirm the feasibility of the defined approach, resulting in a prototype design with a TRL of 3-4. In Phase II, the prototype receiver will be fabricated and evaluated. A TRL of 5-6 will be reached by the end of this SBIR program.","startYear":2012,"startMonth":2,"endYear":2012,"endMonth":8,"statusDescription":"Completed","principalInvestigators":[{"contactId":3164552,"canUserEdit":false,"firstName":"Richard","lastName":"Myers","fullName":"Richard Myers","fullNameInverted":"Myers, Richard","primaryEmail":"RMeyers@RMDInc.com","publicEmail":true,"nacontact":false},{"contactId":393445,"canUserEdit":false,"firstName":"Richard","lastName":"Myers","fullName":"Richard F Myers","fullNameInverted":"Myers, Richard F","middleInitial":"F","primaryEmail":"richard.myers-1@nasa.gov","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"projectManagers":[{"contactId":461333,"canUserEdit":false,"firstName":"Theresa","lastName":"Stanley","fullName":"Theresa M Stanley","fullNameInverted":"Stanley, Theresa M","middleInitial":"M","primaryEmail":"theresa.m.stanley@nasa.gov","publicEmail":true,"nacontact":false},{"contactId":3164243,"canUserEdit":false,"firstName":"Michael","lastName":"Krainak","fullName":"Michael Krainak","fullNameInverted":"Krainak, Michael","primaryEmail":"Michael.A.Krainak@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[{"transitionId":65433,"projectId":9756,"transitionDate":"2012-08-01","path":"Closed Out","closeoutDocuments":[{"title":"Final Summary Chart","file":{"fileExtension":"pdf","fileId":305647,"fileName":"SBIR_2011_1_FSC_S1.01-9291","fileSize":149099,"objectId":65433,"objectType":{"lkuCodeId":1841,"code":"TRANSITION_FILES","description":"Transition Files","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"fileSizeString":"145.6 KB"},"transitionId":65433,"fileId":305647}],"infoText":"Closed out","infoTextExtra":"","dateText":"August 2012"}],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
