Self-mixing interferometry for distance measurement using a semiconductor laser with current-modulated wavelength
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. Advan...
