Based on the current state of technology, distance measurements over a few hundred metres in air with relative uncertainties significantly better than 10_6 are still an almost impossible challenge. In the European Joint Research Project (JRP) “Metr

A multi-wavelength diode laser interferometer for measurement of surface profiles has been developed. Three laser diodes emitting in the near infrared were used. The resulting synthetic wavelengths were approximately 14 µm and 290 µm. The long synt

In this work, we demonstrate two-color inline refractivity compensation in a heterodyne synthetic wavelength interferometer for a measurement of absolute distances over several hundred meters with sub-millimeter accuracy. Two frequency-doubled Nd:YAG

There are a number of approaches to measure absolute distances interferometrically without the need of mechanical guidance [1, 2]. Prospective use in coordinate machine measurements or laser trackers, for example, has driven this field for the last t

We present a tracking interferometer with an intrinsic compensation of the refractive index of air. By using both wavelengths of a frequency doubled Nd:YAG laser the refractive index of air can be determined and compensated by the dispersion. One dim
