Paper Abstract

There are two basic configurations of stereoscopic particle image velocimetry (SPIV) systems: translation system and angular-displacement system. Theoretical and experimental error anaysis of SPIV is summarized. The results of theoretical error analysis indicate that the angular-displacement SPIV system with the Scheimpflug condition can provide up to 40% higher out-of-plane accuracy than the translation systems. Experimental error analysis of SPIV is to directly estimate the uncertainties from actual SPIV recordings after accurate automatic registration provided the imaged object's characteristics are known. Moreover, a liquid prism ensures that two camera continue to enjoy an orthogonal orientation with respect to the liquid-air interface.
