Abstract
This paper presents a two-color optical path-1ength-cdulated reversible fringe-counting interferometer system for iieasuring the change of the air refractive index. By measuring the changes of the optical path for infrared and visible light the interferoieter cancels the effect of the geoietrical distance change. This system is being tested over a 235 ii path in the tunnel at NRLM. 1.
