UHF-120高頻顯微激光測振儀
UHF-120 超高頻激光測振儀的顯著特點是其具有極大的測量帶寬，可高分辨率對高達 2.4 GHz 的面外振動進行全場分析。UHF-120具有小于1μm的高橫向分辨率，這尤其對聲表面波 (SAW) 分量的表面波可視化起決定性作用。另一個應用涉及驗證體聲波 (BAW) 分量和超高頻率范圍內超聲換能器成像。
UHF-120測量結果包含大帶寬范圍內的振動信息，可一次性快速地識別諧振頻率。通過安裝在軟件控制的高精度xy 工作臺的樣品移動，完成全場測量。

Next generation micro- and nanotechnology devices such as micro-acoustic filters, RF-MEMS and ultrasonic transducers involve high frequency mechanical vibration and wave propagation approaching GHz frequencies. For microscopic devices operating at these frequencies only sophisticated optical techniques can provide the spatial resolution, zero mass loading and vibration sensitivity required for proper characterization.
UHF-120 Ultra High Frequency Vibrometer captures real-time, out-of-plane motions of micro devices with picometer sensitivity and a measurement bandwidth of up to 2.4 GHz. Options provide for either a manual point-by-point system (VibSoft) or an automated scanning system (PSV Soft) capturing and analyzing deflection shapes.
