Pressure measurements are made by measuring Bragg grating peak splitting caused by transverse strain differences in the core of a single mode side hole fiber. The side holes and not the fiber exterior are pressurized, demonstrating the ability to use the side holes as a pressure conduit so that pressure measurements can be made in a thermally and(More)
The feasibility of using multi-axis fiber grating strain sensors to monitor transverse strain and transverse strain gradients to complex, woven composite structures has been evaluated. This paper overviews the multi-axis fiber optic grating strain sensors and how they can be applied to measuring multidimensional strain fields interior to composite parts(More)
Multi-axis fiber grating strain sensors have been used to quantitatively measure axial strain and temperature, transverse strain and transverse strain gradients in composite weave structures. This paper overviews the multi-axis fiber optic grating strain sensors and how they can be applied to measuring multidimensional strain fields interior to complex(More)
