Abstract

A high-speed three-dimensional measurement system was demonstrated using an electronically controlled wavelength-tunable ultrashort pulse fiber laser and an all-fiber interferometer. A longitudinal scanning range of 2.8mm and a scanning speed of 100,000  pointss were achieved without moving parts. For a measurement distance of 0.7m, the sensitivity and accuracy were 70dB and ±8μm, respectively. A clear three-dimensional image of a 100 yen Japanese coin was obtained using this measurement system.
