摘要
In this article, we proposed an all-fiber laser self-mixing rangefinder by using the fabricated tunable fiber ring cavity laser with the wide-band tunable fiber Fabry-Perot filter as the frequency selective device instead of the traditional fiber grating. It has been shown to be of great significance in the measurement of the absolute distance with larger dynamic range and higher measurement accuracy. Additionally, the wavelength tuning range and frequency are controlled by adjusting the modulation signal introduced into the tunable fiber Fabry-Perot filter. In experiment, the absolute error and the relative error are inferior to ±0.047 m and 0.32% respectively within the range of 15 m, of which are satisfied with the measurement requirements of the reliable accuracy and broad range absolute distance.
