Abstract: In this work, we propose a method using frequency-modulated continuous-wave (FMCW) self-mixing interferometry (SMI) and all-phase fast Fourier transform (APFFT) for simultaneous measurement of speed and distance. APFFT offers superior accuracy in frequency determination by… read more here.
