Highly-sensitive and high-resolution all-fiber three-dimensional measurement system
TL;DR: A practical all-fiber three-dimensional measurement system is demonstrated with an incoherent interferometer at the eye-safe wavelength of 1.55 mum and the resolution, sensitivity, speed, and angle dependence are discussed for measurement of a 100 yen Japanese coin.

Three-Dimensional Optical Measurement with Spectroscopic Function Using Fiber Laser Supercontinuum
TL;DR: In this paper, a 3D measurement system with spectroscopic function was demonstrated using a practical supercontinuum light source and an all-fiber interferometer, where the spectral information was obtained by Fourier transformation of the observed interference signal.
