High-resolution distance meter using optical intensity modulation at 28 GHz
A high resolution distance meter has been fabricated using optical waveguide modulators. The meter was evaluated in the National Research Laboratory of Metrology (Japan) semi-underground tunnel. The measurement resolution is 1 and 3 \#m\m for a distance of 5 and 100 m, respectively, in one standard...

| Zusammenfassung: | A high resolution distance meter has been fabricated using optical waveguide modulators. The meter was evaluated in the National Research Laboratory of Metrology (Japan) semi-underground tunnel. The measurement resolution is 1 and 3 \#m\m for a distance of 5 and 100 m, respectively, in one standard deviation after correction of the cyclic error. Cyclic errors are examined for 28 GHz optical intensity modulation. (Original abstract - amended) |
