The Angle spectrum analysis of self-image of double frequency grating is given. The grating duplication and the measurement of lens focus are obtained by Tablot effect of holographic phase grating.
In this dissertation, we mainly focus on the research and realization of fiber Bragg grating networks, including the principles and experiments of sensing and demodulation techniques.
