Assembly for Simplified Hi-Res Flow Visualization

Researchers at NASA’s Langley Research Center have developed a simple, compact, easy-to-use projection focusing schlieren imaging system optical assembly that leverages a light source, a single physical grid element, and polarization optics to enable hi-res flow visualization. The assembly can simply be mounted in front of a camera to enable focusing schlieren imaging capability. It was designed to drastically reduce the complexity and time required to align a focusing schlieren imaging experiment.
