LIT-6 Dhexdhexaadiyaha saxda ah

Sharaxaad Gaaban:

Qalabkani wuxuu isku daraa interferometer Michelson, Fabry-Perot interferometer, iyo Twyman-Green interferometer hal madal.Naqshadaynta xariifnimada leh iyo qaab dhismeedka isku dhafan ee qalabku wuxuu si weyn u dhimi karaa wakhtiga isku-habeynta tijaabada wuxuuna wanaajin karaa waxtarka tijaabada.Isla mar ahaantaana, dhammaan qaybaha qaab-dhismeedku waxay ku xiran yihiin madal yar oo culus, taas oo si wax ku ool ah uga hortagi karta saameynta gariirka ee tijaabada.Michelson, Fabry Perot, prism iyo lens faragelinta u dhexeeya afarta hab si fudud ayaa loo beddeli karaa, hawlgalka fudud, natiijada saxda ah, content tijaabo waa qani, waa qalab ku haboon in la fuliyo isku darka tijaabada faragelinta.
