Synthetic interferometric distance-measuring system using a CO2 laser

Abstract

A new synthetic interferometric distance-measuring (SIDM) system is described using two-wavelength simultaneous (synthetic) interferometry with a CO2 laser. The measuring procedure of the SIDM system is based on phase measurement such as with conventional light-modulation distance-measuring instruments. The SIDM system is excellent in length resolution since it uses the synthetic wavelengths of 5.5 mm and 300 μm and a regular single wavelength, interferometrically. It is applicable to the measurement of distances up to 100 m with an accuracy of 1 × 10−7. Its performance is confirmed by comparing it with an HP laser interferometer using a 50-m movable carriage in the NRLM 300-m optical tunnel.
