Abstract Structural mechanical vibration is commonly measured through punctual sensors, i.e. sensors that measure the structural behavior at only one point. Examples of such sensors are accelerometers, LVDTs, non-scanning laser vibrometers, and proximity probes. This project aims at developing an acquisition system able to measure the dynamic behavior of a structure as a whole (many points) using only one sensor: a video camera. After video image acquisition, the vibration at specific points of interest is obtained by computer post processing, adopting image processing techniques. The objective is to develop a system able to measure orbits and operational modes of a rotating system in operation. | |
