我们将光散射应用于来自Sandia透明引擎的物种、空间和时间分辨率图像的产生，该引擎与丙烷和空气一起运行。通过适当调谐我们的KrF激光器，并用适当的滤光器处理散射光，我们可以通过瑞利散射成像(A)总密度(从而温度)，以及(B)通过激光诱导荧光成像OH和热O2的密度(即振动态6和7)。
We apply light scattering to the production of species-, space-, and time-resolved images from a Sandia transparent engine, which operates with propane and air. By appropriate tuning of our KrF laser, and by treating the scattered light with an appropriate filter, we can image (a) the total density (and thus the temperature), via Rayleigh scattering, and (b) densities of OH, and of hot O2 (i.e., vibrational states 6 and 7) via laser-induced fluorescence.
