Power Spectral Density

How PSD is used to specify many types of Optics

Power Spectral Density (PSD) is a very useful concept when it comes to specifying many types of optics and has been proven to be a valuable metric in extreme application spaces such as laser fusion. This specification method can also be applied to demanding applications, high energy laser optics, particularly because it helps in understanding and managing the quality of optical surfaces in a detailed way not captured by conventional methods.
