{"Image DocumentName": "Distancemeter with micrometer resolution", "Image ImageDescription": "CONCLUSION. Distancemeter with micrometer resolution. Accuracy better than 10 \u00b5m (could be improved by considering electronic crosstalk) Outdoor with quiet environment, demonstration of measurements over 864 m. Reproducibility of 20 \u00b5m demonstrated over 120 m. Difficult to use with \u00ab very \u00bb perturbated atmosphere. Still limited by temperature measurement for long distances (target uncertainty not reach) Possibility to include dispersion temperature measurements with YAG lasers (PTB already demonstrated over 100 m) Transportable distance measurement system based on superheterodyne interferometry using two phase-locked frequency-doubled Nd:YAG lasers , S.
