A line illumination (or bar illumination) describes a light source that produces a line-shaped light structure. Examples are light-emitting diode arrayswith a cylindrical lens or a laser with attachment optics.

They are used for targeted illumination for line scan camera applications (line illumination) or for light sectioning processes with matrix cameras (e.g. laser triangulation). Line lighting in incident light is used as standard for surface inspections with line scan cameras. They are also used as transmitted light or as dark field illumination.
