Webtemporal and spatial coherence by amsh Coherence can be classified into two ways: a) temporal coherence: consider a light wave traveling along +X axis. Consider two different points A and B along the same wave train that is along +X axis. If Φ (A) is phase of point A at any time and Φ (B) is phase of point B at any time, then WebFeb 18, 2024 · Measuring unit of Spatial Coherence. Usually, the temporal coherence of light is described with the coherence length. This quantity can be measured conveniently with an interferometer and is directly related to the coherence time and the spectral bandwidth. It is often stated in the data sheets of lasers. elysis bourse
