For the two-step phase-shifting methods, there are only two equations which can be established. These two equations are less than the three unknown parameters; (1) background term (or carrier), (2) ...
Coherent beam combination has emerged as a promising strategy for overcoming the power limitations of individual fibre lasers. This approach relies on maintaining precise phase difference between the ...
Optical metrology, as a general-purpose metrology technique that uses light as information carriers for non-contact and non-destructive measurement, is fundamental to manufacturing, basic research, ...
