Line scan mode represents a cost-effective alternative to a line scan camera
Line scan mode is indispensable for many applications in industrial machine vision, such as the analysis of curved surfaces or endless web inspection. If objects cannot be captured in their entirety in a single exposure due to their size or shape, they have to be "scanned". The camera captures information line by line to build up a picture of the object in its memory that is free of any perspective distortions or non-homogeneous lighting. When line scan mode is used, movement is essential – either the material to be inspected is moved, e.g. on a conveyor belt, or the camera itself moves, in which case a clock is required.
