Determining system parameters and target movement directions in a laser self-mixing interferometry sensor

HIGHLIGHTS

• who: Bin Liu and colleagues from the School of Physics and Optoelectronics, Xiangtan University, Xiangtan, China have published the research: Determining System Parameters and Target Movement Directions in a Laser Self-Mixing Interferometry Sensor, in the Journal: Photonics 2022, 612 of /2022/
• what: The authors present comprehensive analyses on SMI signal waveforms for determining system parameters and movement directions by a single-channel weak feedback SMI signal. The authors mainly investigate the symmetry of SMI signals when C ≤ 1.
• how: Based on the waveform analyses the authors proposed a method to estimate LEF . . .
