1	Line scan camera: Scans the image line by line and communicates with the PC.	2	Optical system: Lenses and mounts
3	Illumination: Lights up the information carrier/scan area.	4	Illumination controller: Controls and monitors the illumination unit.
5	Cables and suitable network card or frame grabber in the PC: The image data are sent to a PC.	6	PC: The PC performs subsequent processing of the image data and can optionally control the illumination system.
7	Speed detection: The speed of the object/conveyor belt can be detected by an optional incremental encoder. The encoder can be connected to the camera.	8	Conveying unit: Moves the scanned object.
9	Frame trigger: A light barrier can be used to detect the object and start the image acquisition on time. The frame trigger can be connected to the camera.
