This Small Business Innovation Research (SBIR) Phase I project will develop a Two-Photon Resonant Holography (TPRH) imaging technique capable of recording time-resolved number densities of atomic or molecular species. Resonant holography and the innovative application of two-photon absorption and photorefractive quantum well (PRQW) holographic devices will allow the development of high-speed systems using only low-cost, solid-state components. Phase I will develop the TPRH technique by constructing a prototype system and demonstrating its operation with a selected species. The use of two-photon absorption with resonant holography allows visible or infrared (IR) lasers to probe species with ultraviolet (UV) absorption lines. Costly UV lasers and optics can be avoided. The PRQW device enables high recording rates. These devices are capable of kiloHertz or megaHertz rates with energy requirements in the nanojoule range.Commercial applications are expected in industrial and fundamental research areas: combustion, plasmas, reacting flows, in vitro biomedical testing, supersonic mixing and reacting flows, and basic research into the nonlinear behavior of atomic or molecular electronic systems. Furthermore, TPRH may find applications in very low cost video rate systems; lightweight, low-power airborne or space-based systems; and multiple-view systems for tomographic measurements.

这个小企业创新研究（SBIR）第一阶段项目将开发一种双光子共振全息（TPRH）成像技术，能够记录原子或分子物种的时间分辨数密度。 共振全息术和双光子吸收和光折变量子阱（PRQW）全息器件的创新应用将允许开发仅使用低成本固态组件的高速系统。第一阶段会发展第三方式租住房屋技术，建造一个原型系统，并示范其在选定物种上的运作。 使用双光子吸收与共振全息允许可见或红外（IR）激光探测紫外（UV）吸收线的物种。 可以避免昂贵的UV激光器和光学器件。PRQW器件能够实现高记录速率。这些器件能够以千赫兹或兆赫兹的速率工作，能量要求在纳焦耳范围内。商业应用预计在工业和基础研究领域：燃烧，等离子体，反应流，体外生物医学测试，超音速混合和反应流，以及原子或分子电子系统非线性行为的基础研究。 此外，TPRH可以在非常低成本的视频速率系统中找到应用;轻型、低功率的机载或基于空间的系统;以及用于断层摄影测量的多视图系统。
