Vpliv bočne refrakcije na merjenje horizontalnih smeri : diplomska naloga

Cergol, Katja (author), Ambrožič, Tomaž (mentor), Štebe, Gašper (co-mentor)

Teoretični del diplomske naloge, ki je razdeljena na dva dela, opisuje refrakcijo kot fizikalni pojav. V prvem delu so predstavljene osnovne lastnosti svetlobe kot elektromagnetnega valovanja z osnovami lomnega zakona, v drugem delu pa je refrakcija predstavljena kot pogrešek, ki se pojavlja pri geodetskih meritvah. V praktičnem delu naloge je na podlagi terenskih meritev predstavljena izmera horizontalne refrakcije. Vpliv smo skušali prikazati pod različnimi pogoji, in sicer glede na temperaturo, oddaljenost vizure od objekta, oddaljenost objekta od instrumenta in glede na dolžino vizure, pri čemer smo za objekt vzeli osebni avtomobil. Nato smo s pomočjo enačb, ki so predstavljene v tuji literaturi, poskušali izračunati refrakcijski kot in njegov vpliv na meritve.

• Title: Influence of lateral refraction on measured horizontal directions

Abstract

The theoretical part of the thesis is divided into two parts and it describes the refraction as a physical phenomenon. The first part represents the basic characteristics of the light as an electromagnetic wave acoording to the law of refraction. The second part presents the refraction as a measurement error, which shows up in geodetical measurements. The practical part presents the reading of the horizontal refraction, based on the field measurement. Our goal was to describe the influence under different circumstances, such as: the temperature, the distance of line of sight from the object, the distance of the object from the instrument, and the length of line of sight. The object of our measurement was an automobile. With the help of the equations presents in foreign literature, our next step was to calculate the angle of refraction and its influence on the measurements.
