Vibration measurement by vibrating-plate holograms

Optics Communications, 1973
Abstract If a hologram of a vibrating object is recorded on a photographic plate which vibrates synchronously with the object, the reconstructed image produces equi-amplitude fringes of the object vibration, the amplitude of which is reduced by a constant determined from the amplitude of the plate vibration. This phenomenon can be used as a method to

Vibration Measurement System

The Journal of the Acoustical Society of America, 2011
The invention relates to a vibration measurement system for frequency-selective oscillation measurement in particular of low frequencies as are relevant in the field of automation and drive technology. The invention proposes coupling a broadband transmitter structure, which is excited directly by the excitation signal to be determined, via an ...

Vibration Measuring System

The Journal of the Acoustical Society of America, 2011
The invention relates to a vibration measuring system for the frequency-selective measuring of especially low-frequency vibrations such as they are relevant in the area of automation and motive power engineering. The aim of the invention is to provide a system which allows an economical vibration analysis of frequencies in the range of from 0 to 1 kHz.

Cable vibration — Methods of measurement

Electrical Engineering, 1936
Test methods and equipment developed for the laboratory production in cables of vibrations (standing waves) similar to those experienced in transmission line service, and for determining the relative susceptibility of different cables to conditions tending to produce vibrations, are described.
