In Physics, What Is Coherence Length?
In physics, the coherence length refers to the distance that coherent waves (such as electromagnetic waves) maintain a certain degree of coherence to propagate. The larger the coherence length and the longer the coherence time, the better the time coherence of the light source. [1]

- In a radio-band system, the coherence length can be roughly calculated using the following formula [1]
- Multimode
- Coherence time
- Superconducting coherence length
- Spatial coherence
