Abstract

A new idea of measuring video flutter of VTR is proposed in this paper. Based on the Laser Doppler Anemometry, the instability of a working piece can be studied by inspecting its instantaneous speed. Experiments show that this method can realized non-contact measurement while the VTR is playing, and can be used to analyze the dynamic characteristics of other kinds of rotating machinery.
