Sensitivity Enhancement of a Self-Mixing Laser Diode Sensor by Using a Dual-cavity Configuration

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, the laser output power will be modulated. This is called Self-Mixing Effect (SME), which is a universal phenomenon occurring in lasers regardless of type. For SME base...
