Scanning 3D laser vibrometer for non-contact in-plane and out-of-plane vibration measurement

所要求的3D扫描激光测振仪用于表征小型和大型、简单和复杂结构的3D振动，目的是了解振动行为，作为优化噪声和振动控制策略的先驱。它适用于不可能或不切实际使用接触式传感器的小物品，以及振动场可能复杂且3D扫描能力必不可少的大型结构。例如微定位致动器、压电式电机、带电电池响应、盘式刹车、飞机和车辆。成果包括加强现有的研究项目，使人们能够更好地了解噪音和振动现象。

The requested 3D scanning laser vibrometer is intended for the characterisation of 3D vibration of small and large, simple and complex structures, for the purpose of understanding the vibratory behaviour as a precursor to optimising noise and vibration control strategies. It has application to small items for which the use of contact sensors is impossible or impractical, as well as large structures for which the vibration fields can be complex and a 3D scanning capability is essential. Examples include micro-positioning actuators, piezo-electric motors, live cell response, disk brakes, aircraft and vehicles. Outcomes include the enhancement of existing research projects, allowing a greater understanding of the noise and vibration phenomena.
