Optical component technologies are grouped in the following categories: ultraviolet imaging, wide field of view imaging for near-Earth asteroids, and instruments for quantum interferometry. These improvements in optical components must complement improvements in associated detectors.","exampleTechnologies":"Mirrors, lenses, interferometers, gratings, prisms, fibers, dynamic pointing components (e.g. field steering mirrors), active optical elements, advanced surface technologies (e.g. frequency selective surfaces and composites), ground metrology and systems","hasChildren":false,"hasInteriorContent":true}],"startTrl":1,"currentTrl":3,"endTrl":3,"benefits":"The proposed technology will be applicable to a wide variety of applications for which a spectrometer is needed to characterize or quantify chemicals of interest, but where size and cost are at a premium. NASA missions that may specifically benefit from hybrid LGI infusion include Earth Science and Planetary Exploration. Sample applications within these broader research areas include characterization of sulfur dioxide emissions from volcanoes, monitoring of methane pipelines, remote sensing from UAV platforms or in situ characterization of samples from a rover.
As environmental regulation of emissions increases, the market for compact, low cost chemical sensing technologies similarly increases in order to demonstrate compliance. In addition, natural gas companies require a method to monitor their pipelines to prevent significant losses and to minimize the environmental impact of their operations. A compact, low cost system that could be integrated into a drone platform would effectively address these needs.","description":"NASA is interested characterizing the atmospheric concentration of greenhouse gases critical to global warming phenomena, and their fluxes over time. For this reason, NASA has invested in the Total Carbon Column Observing Network (TCCON), which comprises sun trackers with high resolution Fourier Transform Spectrometers. NASA is currently looking to expand their observation network in order to provide more data for their atmospheric research, but this will require a reduction in spectrometer size and cost. OPTRA proposes to address this need through the development of a novel hybrid spectrometer design that leverages the strengths of Michelson and lamellar grating interferometers, while mitigating their individual weaknesses. The end result will be a compact, rugged, low cost spectrometer capable of the same performance as the current TCCON network. This technology will further be extendable to any applications where spectral data is required, but instrument size and cost are at a premium. Examples include methane pipeline monitoring, volcano emission characterization or UAV-based remote sensing.","startYear":2015,"startMonth":6,"endYear":2015,"endMonth":12,"statusDescription":"Completed","principalInvestigators":[{"contactId":138555,"canUserEdit":false,"firstName":"Elizabeth","lastName":"Schundler","fullName":"Elizabeth

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.
