文摘

Colour sequence illumination system is developed to mark time sequence of bubbles. A prototype of colour sequence enhanced particle streak velocimetry was built. Relative error of CSPSV is blow 5% for normal speed in ventilated space. CSPSV is more effective in streak matching and high speed 3D path tracking.
