Abstract: The capabilities of the method of current-modulated laser wavelength are shown to be extended by using harmonic modulation. Advantages of the sawtooth modulation method associated with using the frequency measurements of the interference signal as an information parameter have been researched. Advantages of the harmonic-type modulation based on the use of measurement results for spectral component amplitudes of the interference signal for distance determination have also been investigated. A comparative analysis of methods for absolute distance measurements at the existing capabilities of semiconductor laser wavelength modulation has demonstrated the benefits of the harmonic modulation of laser diode current for distances under 30 cm, showing the sawtooth current modulation to work better for distances greater than 50 cm.
Keywords: semiconductor laser, self-mixing interferometry, distance measurement, wavelength modulation.
