In this research, we propose a novel approach that allows the phase-shift measurement of chirped amplitude-modulated signals: the chirped amplitude-modulated phase-shift (CAMPS) method. With this method, we can make use of the advantages of Dispersion-tuning swept lasers (DTSL) and for the first time realize an overall non-mechanical spectrally scanned LiDAR system. An axial ranging RMS error of ~200 μm at a scanning speed of 10 kHz can be achieved with the compensation of the systematic error, which corresponds to a phase resolution of 0.35°.
