In particular, SSC would like to develop a sensor to monitor the quality of LOX in the delivery line during the testing of a rocket engine. Spontaneous Raman scattering (SRS) with its relative simplicity and multi-molecule analysis can be easily employed to develop a sensor for on-line, real-time measurement. In Phase I we have designed an initial - prototype system for gas mixture and LN2.measurement. This proposed Phase II research is to design an integrated Raman system that will improve the sensor performance to satisfy NASA's need for LOX quality control. A calibration technique for the gas phase sensor will be developed. An optical access interface unit for the LN2/LOX mixture system will be designed. The performance of the integrated Raman system with LN2/LOX mixtures will be evaluated and the final prototype Raman system will be delivered to NASA/SSC.

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.
