Abstract

A method is described for the measurement of basilar membrane (BM) vibration velocimeter (LDV). The instrumentation was coupled to a compound microscope which served to visualize reflective glass microbeads placed on the BM. The laser beam of the LDV was focused in the microscope object plane and positioned over the reflective bead. We show examples of frequency tuning curves and displacement input/output intensity functions obtained with the technique.

摘要

描述了一种测量基底膜（BM）振动速度计（LDV）的方法。该仪器与一台复式显微镜相连，该显微镜用于观察放置在基底膜上的反射性玻璃微珠。LDV的激光束聚焦在显微镜物平面上，并定位在反射珠上方。我们展示了用该技术获得的频率调谐曲线和位移输入/输出强度函数的示例。
