BitSim NOW has developed an CD inspection system, to be integrated in a machine for manufacturing CDs. BitSim NOW made a market research and selection of the fast CCD line scan camera which loads an image of the CD-writer when it spins one revolution. The image is sent to one of BitSim NOWs developed frame grabber boards, where some image processing is performed in hardware. Afterwards the image is processed with software vision algorithms, developed by BitSim NOW. After that the image is searched for surface defects, etc. Over 400 machines were manufactured using this equipment.
