What is interferometric coherence?
1 Answer
Interferometry is a technique in which electromagnetic waves are superimposed(Interference) to get information.
Explanation:
Interferometry is an outstanding investigative physics technique.
Interference is like the addition of wave functions.
There are constructive type, when waves add together to create a wave of greater amplitude; and destructive type, when they subtract from each other, creating wave of less amplitude.
Coherence length is the propagation distance over which a coherent wave such as an electromagnetic wave maintains a specified degree of coherence .
Two wave sources are said to be coherent if they have a constant phase difference and the same frequency .
It is an ideal wave property that enables stationary interference such as temporary and spatial interference. Despite being ideal, it is now considered to be an essential concept in quantum physics .
This property describes all properties of the correlation between physical quantities of a single or several waves.
