title: Absolute distance measurements by CO(2) laser multiwavelength interferometry.
abstract: This paper describes a CO(2) laser interferometer allowing absolute distance measurements using a set of CO(2) lines. The method relies on the so-called fractional fringe technique. First, we introduce some theoretical topics related to this application of CO(2) spectroscopy. The second part of the paper is a description of the instrument.
