Robust detection of interferometric fringes is critical for accurate sensing by self-mixing interferometric (SMI) displacement sensors. Mode-hopping of a laser diode (LD) can potentially diversify SMI fringes, transforming them from mono-modal to multimodal. Thus, fringe detection of a multimodal SMI signal becomes a bigger challenge as the relative strength of each mode may be different, leading to further diversity in the fringes belonging to each regime. Also the SMI signals from each mode are incoherently added, so th
