We developed a point-fluorescent-source-based white-light interferometer for high-resolution reflectometry, range-gating imaging, and group-velocity-dispersion measurement. The laser-pumped point fluorescent source has 9 mW of power and a spatial coherence of 0.97, which allows it to be used like a laser beam. Owing to its 40-nm FWHM spectral width, the(More)
Thin-walled cylindrical shells are commonly used in engineering fields; examples include civil engineering structures, offshore oil platforms, submarine pipes, and aircraft fuselages. Due to the problem with local buckling, these shells have failure loads significantly lower than the ones predicted by linear theory. Currently, stringers and ring-stiffeners(More)
