Determining System Parameters and Target Movement Directions in a Laser Self-Mixing Interferometry Sensor

Self-mixing interferometry (SMI) is a promising sensing technology. As well as its compact structure, self-alignment and low implementation cost, it has an important advantage that conventional two-beam interferometry does not have, i.e., SMI signal fringe evolves into asymmetrical shape with increa...
