Method and apparatus using laser radiation for generating and measuring gas bubbles |
摘要 |
A non-intrusive method and apparatus for performing qualitative analysis of a liquid disposed within a container transparent to laser radiation comprises a first laser focused at a selected point within the liquid to produce or generate bubbles emanating from that location and a laser Doppler velocimeter which is intercepted by the rising bubbles to produce an output signal indicating both bubble size and velocity, as indication of liquid quality.
