Sereni, Giulia The study of Newton's rings for alignment of astronomical's instruments. [Laurea triennale]

Full text disponibile come:



This thesis underlines the importance of the alignment of optical instruments as necessity for observing the Sky and scienti_c research. Since Newton's rings play a relevant role in the procedure of centration, my thesis focuses on the displacement of it caused by decentering of a lens. A procedure which connects this two factors is presented and veri_ed in laboratory. ln this way this thesis is a con_rmation that Newton's rings are useful during alignment. Ultimately, since we know that the minor error of centration we make the best performance we get, the centering precision of the mounted lens is calculated. ln detail, Chapter 1 gives only the prerequisites usefulfor the understanding of the entire thesis. Chapter 2 is an excursus of actual telescopes and satellites, such as the Large Binocular Telescope and PlAnetary Transits and Oscillations of stars, whit a short description of alignment of their optical components. The formation of NeMon's rings is explained in Chapter 3 both in its historical terms and as interference of two reections. ln the laboratory, we reproduced an optical setup in order to see Newton's rings and con_rm the linear relation between the decentering of a lens and the displacement of Newton's rings: this is discussed in Chapter 4. Moreover, the images and results taken with a Charge-Coupled-Device are also reported
