Abstract
A simple optical technique for the measurement of critical speed and the corresponding modeshape is proposed and tested. In comparison to other optical modal testing techniques reported in the literature, the proposed technique does not involve expensive instrument and complicated signal processing for frequency extraction from the measured frequency spectrum. Moreover, the proposed one is a real-time and full-field measurement technique. It does not require laser and therefore vibration isolation of the measuring instrument is not demanding. The measurement procedure is straightforward and is suitable for workshop implementation.
