Aircraft engines implement multiple safety measures to prevent accidents in advance. In particular, the measurement of turbine blade vibrations is crucial for preventing blade damage, maintaining quality, and ensuring safe operations. Aircraft engines, which require maximum safety like airplanes, need to measure the vibrations of all internal blades. Our VibroMap1000 can measure not only at a single point in a non-contact manner and in a short time but also across the entire surface. Typically, for large structures, multiple accelerometer pickups are installed to perform modal analysis; however, the slight weight of the accelerometer pickups can change the vibration modes themselves. In high-frequency vibration mode analysis, such as that of turbine blades, it is difficult to measure with only a limited number of accelerometer pickups. The VibroMap1000 utilizes speckle interferometry and a CCD camera to irradiate the entire measurement surface with laser light, allowing for real-time measurement of the vibration state, which is extremely useful for reducing measurement and maintenance time.
