Detection of Multimodal Fringes for Self-Mixing-Based Vibration Measurement

IEEE Transactions on Instrumentation and Measurement, 2020
Correct detection of interferometric fringes is necessary to enable high-resolution metric measurements using laser diode (LD)-based self-mixing (SM) interferometry. For noisy, experimentally acquired SM signals, fringe detection (FD) is a challenge even
