| Abstract(in English) | A semiconductor laser's frequency fluctuates owing to the refractive index fluctuations caused by the spontaneous emission in a laser cavity. In this study, a new application of semiconductor laser's frequency noise characteristics is discussed. We propose a new laser rangefinder using the semiconductor laser's frequency noise. This method calculates the correlation between the divided laser beams and determines the optical distance without any modulation, and its accuracy are expected unchanged even in a long distance measurement. We measured the distance from 0 to 35m using the proposed method. |
