SBIR-STTR Award

We propose to build a MHz rate, high-resolution imaging device that can be used to measure MHz rates imaging flows in hypersonic wind tunnel technology. The MHz rate laser imaging device will have very compact size (shoebox size), be simple to operate, and extremely reliable. The performance of the proposed system will surpass the state-of-the-art device developed to date. The proposed system characterized by it high energy laser pulses with a 10-12 second pulse-width, MHz repeatable rates, and a digital record system capable of producing MHz frame rates with high-resolution images that give spatial information on flow properties. The proposed MHz laser-imaging device will be extremely valuable for hypersonic wind tunnel technology. It can be used to assess shock wave and boundary layer fluctuations. It will also be a valuable tool in conjunction with various laser diagnostics such as laser-induced fluorescence, Rayleigh scattering and Raman scattering.

Instruments proposes to build a high frame rate, high resolution imaging device for measuring model position in wind tunnel. This ultra-high frame rate, high resolution laser imaging device will be compact, easy to use, and reliable. The device will have high frame rate from 1000 to 100,000 frame/sec with FOV of 5ftx5ft @ 10 feet stand-off distance, and will be capable of producing 100 frames minimum with 1000X1000 pixel resolution/frame and 14 bit data readout, meeting the requirement of AEDC. The results from the extremely successful Phase I program has provided numerous valuable data and solid foundation for the Phase II work, and thus it is expected that the development of the proposed system can be accelerated. Due to the absence of such imaging device in the market, the program will provide a great opportunity for the commercialization of the high frame rate imaging system.
