Optical metrology

Optical metrology is the science and innovation concerning estimations with light. Such estimations can either target properties of light and light sources or properties of items, for example, measurements, separations and temperatures. There is no exacting limit between those fields, in light of the fact that frequently one uses estimated properties of light to describe a light source, however for different purposes – for instance, optical recurrence metrology is utilized for ultraprecise optical clock.
