The technology used is laser line triangulation based on a laser projector with two parallel lines. The double laser line approach permits local surface slope measurement in addition to 3D-position which can be used for material vibration compensation.
The benefits are that manifested flatness can be measured with high accuracy on material that is subject to vibrations from roller tables and uneven transport.
Our technology platform, ShapeCAT, is designed to handle the double line principle at high speed and high resolution. Since the data from the cameras easily can be higher than 3 GByte/second, they are intelligent with local processing capacity. Heavy calculations are done by dedicated processors close to the sensor chips, which drastically reduce the amount of data. Our cameras communicate by standard Ethernet and standard computers and components are used, which are readily available on the market. This simplifies maintenance and keep the availability of the systems on a high level.
