Structured Light Projection-based single-shot transport of intensity phase imaging for quantitative diagnostics of high-speed flows

A method for quantitative estimation of density in a high-speed flow field is presented, which uses a structured-light beam probe to interrogate the region of interest (ROI). Wavefront distortion suffered by the interrogating beam as it passes through the shock-induced flow field is investigated. De...
