Our system combines 3 applications: scanning, measuring, tracking.
Scanning and measuring
During the scanning (laser) or measuring (feeler) process the optical tracker continuously follows the position and orientation of the scanning head or feeler in real-time. While doing so, one can switch at will, via a Renishaw interface, between feeler (measuring) and laser head (scanning), without loss of zero point.
With the laser scanner any shape can completely be recorded (digitised) in a relatively short time, and against CAD a variance analysis, a numerical evaluation or a reverse engineering can be made. With the laser, even highly reflecting or black surfaces can be precisely recorded, without finishing treatment. Elements that are difficult to access or small, deep elements such as boreholes etc. can additionally, without loss of accuracy, be tactilely recorded. The laser scanner is suitable for the recording of a bone plate, an art object as well as for an entire vehicle. The area of application is almost boundless.
The system has a measuring range of 6 metre or 20 m3. In the entire measuring volume it’s possible to work with laser or feeler, as well as combined (laser and feeler). The system is excellently suited for small to medium sized components. By using targets the measuring range can be extended.
The accuracy, ascertained by the feeler, is:
Measuring range up to 3 metre = 20 µ
Measuring range up to 4.5 metre = 30 µ
Measuring range up to 6 metre = 60 µ
With the tracking application high-speed 3D motion sequences can be recorded and analysed in real-time and it provides vibration and deformation analyses. The targets, mounted on the component, are recognized by the tracker and the 3D motion is recorded. The application can be used versatilely, e.g. in the medical field for the motion analysis of an artificial joint, a spine fixation or vibration analyses of a mechanical part etc.
With the help of the DPR (Dynamic Part Referencing) relative movements between component and measuring system are compensated. This permits measurements in motion.
Per component up to 512 targets can be mounted and their movement be recorded. Up to 4'500 measurements per second are possible. The evaluation can result from single spots or from generated areas.
