Abstract

A practical all-fiber three-dimensional measurement system is demonstrated with an incoherent interferometer at the eye-safe wavelength of $1.55\mathrm{\mu m}$. The sensitivity and axial resolution are as high as $102\mathrm{dB}$ and $1.4\mathrm{\mu m}$ from a few meters’ distance, respectively. A rotating scanner is developed for axial scanning, and a wide longitudinal scanning range of $54\mathrm{mm}$ is demonstrated. The high resolution images of a few samples are clearly obtained at the speed of $52\mathrm{points}/\mathrm{s}$. Moreover, the resolution, sensitivity, speed, and angle dependence are discussed for measurement of a $100\mathrm{yen}$ Japanese coin.
