  • Cure monitoring of a UV cured epoxy resin using a long period grating Mach- Zehnder interferometer 
    Buggy, Stephen J.; Murphy, Richard P.; James, Stephen W.; Tatam, Ralph P. (International Society for Optical Engineering; 1999, 2007-12-31)
    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 ...
  • Multiplexing of Fibre optic long period Grating based interferometric sensors 
    Murphy, Richard P.; James, Stephen W.; Tatam, Ralph P. (IEEE Institute of Electrical and Electronics, 2007-03-01)
    Two long-period gratings (LPGs) fabricated in series in an optical fiber form a Mach-Zehnder interferometer, producing a sinusoidal channelled spectrum within the characteristic LPG attenuation bands, which has the ...
  • Nested long period grating interferometers 
    Murphy, Richard P.; James, Stephen W.; Tatam, Ralph P. (International Society for Optical Engineering; 1999, 2007-12-31)
    The concept of nested fibre optic long period grating (LPG) based interferometers is introduced. A number of in-series, identical LPGs may be used to form a set of nested, multiplexed Mach-Zehnder interferometers that ...
