W hen two or more light waves interact with one another, they result in the formation of different interference patterns. British physicist Thomas Young first demonstrated and explained these ...

A density plot of Talbot intensity in a single period transversely (across the grating) and longitudinally (along the direction of the incident light). The colour coding is the same as in figure 2.

Interference measurement involves measuring the phase difference between two light beams from the interference intensity. By using a plane wave (a light wave with a uniform phase distribution) ...
