摘要：While performing geodesic tasks of highest fidelity in machinery production plants, ironworks, rolling mills etc. – including monitoring of the geometry of production lines, geodesic measurements of dislocations and deformations of gravity dams and many other kinds of geodesic tasks, laser alignmetric methods have been used for decades. An important disadvantage of these simple optical methods lies in the negative impact of geodetic refraction on the path of the laser beam. This paper presents a theoretical mathematical-physical model for calculating refraction adjustment (line corrections) including a sample calculation.
