要約(英語): Measurements performed using the self-coupling effect of a semiconductor laser utilize an external resonator by exploiting the reflected light from the surface of an object. The improvement of the measurement accuracy due to the use of self-coupled signals acquired from terminal voltages has not been thoroughly investigated. The current that flows through a semiconductor laser is adjusted so that its wavelength changes at a specific rate when it is modulated using an arbitrary waveform. As such, the spread of the self-coupled signal is suppressed, and precision is improved. In addition, the accuracy is improved by considering the influence of lenses on the optical path.
