This paper describes a real-time vibration spectrum imaging system that uses a pixel-level
short-term Fourier transform (STFT). This pixel-level STFT function for high-frame-rate …

A position sensitive detector (PSD) is frequently used for the measurement of a one-
dimensional position along a line or a two-dimensional position on a plane, but is more often …

In nuclear power plants, vibration stress of piping is frequently evaluated to prevent fatigue
failure. A simple and fast measurement method is attractive to evaluate many piping systems …

It has been realized and characterized the instrument for low frequency measurement of
mechanical vibration by using optocoupler sensors and cantilever system. The realized …

This paper presents an experimental study of the rabbit eardrum spectral dynamic response
by using the laser interferometric technique. Michelson laser interferometer was setup and …

This paper discusses the used of an optical interferometry technique for bending and
torsional vibrational modes measurement. With this technique, the amplitude and frequency …
