Paper Abstract

The multichannel WDM (Wavelength Division Multiplexing) technique inspired the concept of vibration measurements for many points of a vibrating object. The N-independent WDM separated 15XX nm fibre coupled laser diodes (used for optical fibre telecommunication) form coherent system of sources for multipoint measurement of vibrations according to the rule one wavelength - one point. The scattered light from the object coupled into the fibre, filtered coherently, after special signal processing, allows analysing amplitudes and phases of many vibrating points in real time. Some experiments and results of such system will be demonstrated.
