Measurement of Resonant Frequencies of Objects by Rotating Aperture-Stroboscopic Speckle Photographic Method
A new experimental method for measuring resonant frequencies of objects is proposed by use of rotating aperture stroboscopic speckle photographic method. It can easily measure the resonant frequencies of objects with this method. In addition to the advantages of high precision, a better visibility of lines is provided. The theoretical analysis and experimental result are given.
