In many industrial applications and scientific studies of liquid in non-equilibrium states, such as sprays or jets, it is important to know their physical properties as accurate as possible. However, the properties of a non-equilibrium liquid volume can be difficult to be measured due to rapid change, sensitivity to the environmental conditions, and complex co-relation between the properties. Therefore, a technique which enables an instantaneous and simultaneous measurement of multiple physical properties is needed. In this study, we develop a technique that enables simultaneous measurement of the size and the modulation of the boundary of a liquid deformed microjet. We present comparisons of the theoretical resonance structures under various conditions with the experimentally observed cavity-modified fluorescence spectra of a microjet, and determine its boundary profile in the accuracy of 0.01% of the diameter.
