Improving Measurement Sensitivity for a Displacement Sensor Based on Self-Mixing Effect
When a part of light emitted by a laser is back-reflected or back-scattered from an external target and re-enters the laser cavity, both the laser intensity and its wavelength can be modulated. This is so-called self-mixing effect (SME). An SME-based displacement sensor is featured with compact phys...
