Spatial resolution with very high quality standards
The linear camera produces an image formed by a single line of pixels. The complete image is built on board of the computer, using the relative movement between the object and the camera. The object movement is usually synchronized through an encoder.
The linear cameras are used because they can provide high spatial resolution (line of 1024, 2048, …, 8000 pixels), resolutions which are difficult to obtain with the matrix cameras. Typical applications concern the control of continuous productions as tissue ribbons or PVC.
The images obtained with the linear camera can be processed in the same way as those obtained with matrix cameras, and they can therefore be used for quality control, foreign bodies presence, prints alignment, etc …
