line-scan camera

An optical instrument used for quality control purposes that builds a 2D image of an object out of a series of one-line slices of it. Common applications include the inspections of webs, such as sheets of glass, fabric, rolls of paper, aluminum and steel. When used in a stereo configuration, a pair of line-scan cameras can capture two images of the same object from slightly different perspectives, making 3D inspections possible.
