Using the Geodimeter to Measure the Refraction Correction by Dispersion.

Abstract

Accurate measurement of long baselines by optical methods requires a correction for the refractive index of the path. The atmosphere is dispersive to light in the visible spectrum and the effect may be useful for determining the refraction correction in distance measurements. This research investigates the feasibility of using the Geodimeter to measure dispersion with sufficient accuracy to determine refractive index to 1 ppm. (Author)
