Measurement methods – the principle
The laser beam is scanned point by point with a rotating measuring tip. The mirror mount is also moved in a linear fashion to scan the entire beam profile. In this way, a partial beam is diverted and directed at the detector in each instance.
The incoming signal is digitised and transmitted to the evaluation unit. The 14-bit A/D converter and resolution of up to 256 x 128 pixels employed enable an exact analysis even of small disturbances in the raw beam. The device was designed for use in harsh industrial manufacturing conditions, and is adaptable in every spatial orientation.
The software has the following standard functions:
- Measurements: Single, serial measurements (monitor operation) and measurement of chronological development (linescan)
- Displays: Isometry, false colours, contour lines and display of numerical results.
- Data saved in *.foc or ASCII file format.
During the measurement, the entire beam exits the BeamMonitor and must be absorbed as completely as possible.
