Objects in nature and technology vibrate and each vibration depends on the energy input, the material composition and the object structure. In general, vibrations in machines can lead to material stress, wear, noise generation and higher energy consumption and must therefore be optimized. A contactless optical measurement of vibrations without mass input into the vibrating system as with tactile motion sensors offers relevant advantages. For this reason, various working groups at the TU Clausthal are engaged in vibration analysis with a laser Doppler vibrometer (LDV). The applicant has already co-developed 3D scanning laser Doppler vibrometers (3D-RLDV) during his industrial activity, which allow non-contact analysis of vibration behavior, and is applying for such a device in this application for his own research of new technologies in laser Doppler vibrometry. However, a 3D scanning laser Doppler vibrometer will be accessible to all researchers at Clausthal University of Technology for vibration analysis at the Clausthal Center for Materials Engineering. Specifically, however, the system is envisioned in the applicant's research group for outdoor tracking applications and will be used to measure, for the first time, 3D vibrations on moving objects (e.g., moving cars and vibrations generated by these vehicles or wind turbine blades) outdoors. To this end, a device with open interfaces is to be procured and expanded with proprietary software solutions, so that the large-scale device will be used primarily for research into new technology for laser Doppler vibrometry.

自然界和技术中的物体振动，每次振动取决于能量输入，材料成分和物体结构。一般来说，机器中的振动会导致材料应力、磨损、噪音产生和更高的能耗，因此必须进行优化。与触觉运动传感器一样，在没有质量输入到振动系统中的情况下对振动进行非接触式光学测量提供了相关的优点。为此，克劳斯塔尔工业大学的多个工作组使用激光多普勒测振仪（LDV）进行振动分析。申请人已经在其工业活动期间共同开发了3D扫描激光多普勒振动计（3D-RLDV），其允许对振动行为进行非接触分析，并且在本申请中申请了这样的设备，用于其自己对激光多普勒振动测量新技术的研究。然而，克劳斯塔尔理工大学的所有研究人员都可以使用3D扫描激光多普勒振动计，在克劳斯塔尔材料工程中心进行振动分析。然而，具体地，该系统在申请人的研究小组中被设想用于户外跟踪应用，并且将首次用于测量移动物体（例如，移动的汽车和由这些车辆或风力涡轮机叶片产生的振动）。为此，将采购一个具有开放接口的设备，并使用专有软件解决方案进行扩展，以便大型设备将主要用于研究激光多普勒振动测量的新技术。
