The overall goal of the proposed research program is to develop a ruggedized imaging system capable of visualization and analysis of the particle field and product gases in a multiphase blast. This will be accomplished by combining kHz-MHz-rate burst-mode laser technology with tomographic particle field velocimetry (PFV) and new nonlinear particle tracking methods to resolve dense particle fields. The high pulse energies and high repetition rates of the burst-mode laser architecture are critical for volume illumination and wide-angle reflective-plenoptic (WARP) imaging. Quad-scopes will be used to couple four images onto a single high-speed camera or eight images onto two cameras with flexible viewing angles for use in blast chambers with limited optical access. The proposed research program offers critical advances for characterizing the particle and gas-phase evolution of multiphase blasts, including: (i) imaging dense particle fields without shadows created by larger particles, (ii) improved accuracy for velocity and size distributions with a wide dynamic range, (iii) significantly reduced errors from out-of-plane motions, and (iv) measurement of the three-component velocity and acceleration fields in three spatial dimensions. The research team at SE and Purdue University has extensive joint experience in developing burst-mode 3D imaging systems relevant to the proposed program.
