Multi-Channel Vibration Measurements Based on a Self-Mixing Vertical-Cavity Surface-Emitting Laser Array

This paper studied a multi-channel self-mixing interferometric vibration measurement system based on a vertical-cavity surface-emitting laser array. A 1 × 8 laser array was utilized to irradiate multiple positions of a vibrating target to establish independent measurement channels. The reflected lig...
