|Abstract: ||A cascaded long period grating Mach-Zehnder interferometer is used to monitor
the change in refractive index of a UV cured epoxy resin over a cure cycle.
Fourier techniques are used to calculate the phase shift and frequency spectral
amplitude of the associated fringe pattern during the cure. The results are
compared with the refractive index change during cure calculated using a Fresnel
reflection based technique.|
