Metrology is the science of measuring distances.
There are different approaches for optical measuring:
- Time of Flight
- Triangulation
- Interferometry
Interferometry is the most accurate way of
measuring distances. It makes use of the wave properties of light. There are
different interferometric measuring apploaches like Absolute Distance Interferometry (ADI), Speckle
Interferometry (SI), or Mode Locking External Cavity Sensor (MolECL). The
accurancy of all interferometric measuring methods is in the sub-micron range.
