摘要: This work shows the improvements in sensing capabilities and precision of an Optical Microbubble Resonator due to introduction encaging poly(methyl methacrylate) (PMMA) box. A frequency fluctuation parameter σ was defined as a score resonance stability evaluated presence absence system case air- or water-filling cavity. Furthermore, noise interference introduced by peristaltic syringe pumping studied. The measurements showed reduction PMMA box when pump used flowing system.
