A major advantage of using line scan cameras is that they have a very high clock rate (10 – 400 kHz). This allows fast moving objects to be recorded without motion blur. This is essential for continuously moving objects, e.g. non-stop belt conveyors with individual objects, film production or printing machines. In addition, line scan cameras have a high resolution. While current 2D cameras have a resolution of up to 5,000 px in one dimension, line scan cameras exist with up to 16,000 px.
The challenge of using line scan cameras is that the short exposure time requires much brighter lighting. In addition, the traversing unit and clock must have high accuracy in order to trigger the camera several thousand times per second at equidistant points.
