To truly merge multiple feeds, the easiest method is to create an intermediary XML document that you can then parse again using XQuery to filter out the individual information.

Mainly used three methods, including including the F-K domain filter, internal excision and the energy decay method to attenuate multiple and obtained a more ideal result.

A novel method of edge filter demodulation for fiber Bragg grating that use wavelength tunable laser was proposed. Real-time monitoring of the multiple points' dynamic strain could be achieved.
