Description
  • Sluneční derotátor je optomechanické zařízení, které se využívá v astronomii. Je určeno ke kompenzaci rotace obrazu z astronomických dalekohledů. Derotátor se skládá ze třech odrazných ploch, vstupní a výstupní optická osa je shodná s mechanickou osou rotace. Správná funkce zařízení závisí na přesné justáži optických a mechanických částí. Abychom získali vodítko pro justáž, připravili jsme simulaci optického systému derotátoru. Je založen na metodě trasování paprsků jednoduchém programu. Jedná se o úlohu ve 3D prostoru. Umožňuje nastavit odchylku pozice ve třech složkách a úhlu sklonu normálových vektorů všech tří zrcadel. Výsledek simulace jsou směry a polohy výstupních paprsků a jejich odchylek od ideálních hodnot. Výsledky mohou být zobrazeny v grafech jako funkce závislosti odchylek výstupních paprsků na chybě pozice jednoho, dvou nebo všech tří zrcadel. (cs)
  • The Sun derotator is optomechanical instrument that is used in astronomy. It is suitable for compensation of image rotation in an astronomical telescope. It is based on of three reflective surfaces. Input and output optical axes have to be identical with a mechanical axis of rotation. A correct function is dependent on precise adjusting of optical and mechanical parts. So that we have some guidance for adjusting, we have prepared simulation of the derotator optical system. It is based on ray-tracing method in simple software. It is fully 3D task. It allows set deviations of mirrors position in three directions and angle deviation of mirrors normal vectors for all three mirrors. The result of the simulation is direction and position of output ray and its deviation from ideal values. Results could be shown on charts as functions dependences deviations of output ray on position error of one or two or all three mirrors.
