| Zusammenfassung | Coordinate measurements are a standard task in industry. For larger volumes tracking devices are used, which optically measure 3D coordinates by different techniques, e.g. by interferometry or time of flight measurement. For these the refractive index plays an important role for the achievable measurement uncertainty. Within a European joint research program, PTB and SIOS develop a tracking device with internal compensation of the refractive index by using two different wavelengths. In a first step a prototype interferometer was set up for testing the components. First 1D results up to a length of six meters are presented. The prototype turned out to be mechanically not stable enough, but the compensation of the refractive index could be demonstrated clearly. Since this refractive index compensation method increases the uncertainty by a quite large constant factor, a procedure for averaging via optically measured temperatures while retaining the time resolution of the position data was developed. |
