Polytec UHF-120 Ultra High Frequency Vibrometer

高达 2.4GHz 的超高频振动测量

UHF-120 超高频激光测振仪的显著特点是其具有极大的测量带宽，可高分辨率对高达 2.4 GHz 的面外振动进行全场分析。UHF-120具有小于1μm的高横向分辨率，这尤其对声表面波 (SAW) 分量的表面波可视化起决定性作用。另一个应用涉及验证体声波 (BAW) 分量和超高频率范围内超声换能器成像。

实时测量瞬态振动

UHF-120测量结果包含大带宽范围内的振动信息，可一次性快速可靠地识别谐振频率。通过安装在可由软件控制的高精度xy 工作台的样品移动，完成全场测量。久经考验的 PSV 软件能以直观生动的方式显示测量结果。
