Schlieren

An optical technique that detects density gradients occurring in a fluid flow. Schlieren is a German word that means 'striations.' It refers to various shadowgraphic techniques for optical investigations. Variations in density in flow through shock waves and supersonic flow, for example, are sharply visible in tonal gradations.

Schlieren

Schlieren (from German; singular `Schliere`, meaning `streak`) are optical inhomogeneities in transparent material not necessarily visible to the human eye. Schlieren physics developed out of the need to produce high-quality lenses devoid of these inhomogeneities. These inhomogeneities are localized differences in optical path length that caus...
