  • Full-field modal analysis using a DSLR camera [Elektronski vir]
    Javh, Jaka ; Slavič, Janko, 1978- ; Boltežar, Miha
    High-speed camera measurements are increasingly being used in modal analysis to measure full-field response measurements using Digital image correlation and other Optical Flow methods. High-speed ... cameras can be very expensive, this is why this paper aims at measuring and identifying the full-field response using cheaper still-frame cameras, such as DSLR and mirrorless cameras. Using Spectral Optical Flow Imaging (SOFI) full-field operational shapes can be acquired using still-frame cameras. This study demonstrates a hybrid modal parameter identification of full-field mode shapes using an accelerometer and a DSLR camera, for responses far above the DSLR camera frame-rate (demonstrated up to 1 kHz).
