|Issue Date:||Jun-2003||Citation:||Tay, C.J., Quan, C., Shang, H.M., Wu, T., Wang, S. (2003-06). New method for measuring dynamic response of small components by fringe projection. Optical Engineering 42 (6) : 1715-1720. ScholarBank@NUS Repository. https://doi.org/10.1117/1.1570824||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.||Source Title:||Optical Engineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/60881||ISSN:||00913286||DOI:||10.1117/1.1570824|
