Distance Measurement with Harmonic Modulation of Self-Mixing Laser Wavelength at External Optical Feedback

Distance Measurement with Harmonic Modulation of Self-Mixing Laser Wavelength at External Optical Feedback

Background and Objectives: Self-mixing interferometry of absolute distances is currently well represented by the method of frequency modulation of the laser diode supply current (FMCW). In recent years a harmonic modulation of the power current of a self-mixing laser began to be used. The advantage...
