Abstract: We describe the use of an optical fringe projection method to measure the dynamic response of small components. In this method, sinusoidal fringes are projected on a small component using a programmable liquid crystal display (LCD) projector and a long-working-distance microscope (LDM). The image of the fringe pattern is captured by another LDM and a high-speed camera and subsequently processed by the fast Fourier transform (FFT) technique. A simple procedure is described that enables calibration of the optical setup for subsequent amplitude and frequency measurement of small vibrating components. A method that enhances the detection range of the system is also included.
