Incoherent and coherent
WebSep 16, 2024 · It is a very important observation that no light is actually completely coherent or completely incoherent. All light is partially coherent, but some light is more coherent than others. An intuitive way to think about these concepts is in terms of the ability to form interference fringes.

WebMar 31, 2024 · A partially coherent transfer function is more complex than incoherent or coherent because each point on the source will have a different level of coherence with respect to each other source point. The degree of coherence between points is dependent upon a parametric function.

The light from a source, either coherent (e.g., a laser) or incoherent (e.g., an incandescent lamp or an arc lamp), is collected by the illumination optics (e.g., a condenser lens) and projected onto the object.

Spatial coherence describes the ability for two points in space, x1 and x2, in the extent of a wave to interfere, when averaged over time. More precisely, the spatial coherence is the cross-correlation between two points in a wave for all times.
