A Novel Method for Detecting Fe<sup>2+</sup> at a Micromolar Concentration Based on Multiple Self-Mixing Interference Using a Fiber Laser
The concentration of an electrolyte is an optical characteristic of drinking water. We propose a method based on the multiple self-mixing interference with absorption for detecting the Fe<sup>2+</sup> indicator as the electrolyte sample at a micromolar concentration. The theoretical expr...
