①Ukusasazwa kwamandla kwi-spectrum yemitha kusondele kakhulu kukukhanya kwelanga
②Ukusasazwa kwe-spectral kwenxalenye ye-spectrum eqhubekayo phantse kuxhomekeke kutshintsho lwamandla okufaka isibane, kwaye ukusasazwa kwamandla e-spectral phantse akutshintshi ngexesha lobomi.
③Iiparameter zokukhanya kunye nombane zesibane zinokuhambelana okuhle, kwaye imeko yokusebenza ayichaphazeleki kangako kutshintsho kwiimeko zangaphandle.
④ Nje ukuba isibane sivuthelwe, ukukhanya okuzinzileyo kunokufikelelwa phantse ngoko nangoko; emva kokuba isibane sicinyiwe, sinokuvuthelwa ngoko nangoko.
⑤Ukusebenza kakuhle kokukhanya kwesibane kuphezulu, kwaye i-gradient enokubakho incinci.
⑥Ifanelekile ukuboniswa kweemuvi, izibane zokukhangela, iilocomotives kunye nokukhanya kwelanga okulinganisiweyo
