Explore: Noise Intensity

Relative intensity noise (RIN), describes the instability in the power level of a laser. The noise term is important to describe lasers used in fiber-optic

contrast with white noise which has equal intensity per frequency interval. Within the scientific literature, the term "1/f noise" is sometimes used loosely

according to the intensity of the industrial noise. This equation works as an inverse, exponential, relationship. As the industrial noise intensity increases

unit of intensity, which includes sound intensity, is the watt per square meter (W/m2). One application is the noise measurement of sound intensity in the
