Fresnel gashto ka kati meelaha multimedia

In la soo dhaafay, hab xeebta ee baxriyiinta ahaa qaybta ugu khatarta badan ee ay safarka. Sababo la xiriira xaaladaha cimilada kasin ama qarar xeebta ku xayiran keeni karaa waayen a. baxriyiintii badbaadiyay lighthouses dhismeedka fiican sahanka ee wakhtigaas. Muddo dheer on dushooda ay kaliya sii shiday dab ah, il dambe iftiin noqotay laambadihii la shito ilaa korontada bilaabay in la isticmaalo. In qarnigii XIX, iftiinka, ee lagu badbaadinayo nolosha, waxa uu noqonayaa mid la gashto Fresnel dhigaya iftiinka tusaaale ee ugu duwanyihiin oo la arki karo meel fog ka ah.

gashto adag Qeybta waxaa la abuuray by Augustin Fresnel, jirka dadka Faransiis, aasaasaha of aragti ruxruxo iftiinka. gashto Fresnel kooban oo dhumucdiisuna waxay a yar oo siddo-gashan shaqsi ku xiga si kasta oo kale oo la xirrira dhululubo la il light gudahood. siddooyinku waxay leeyihiin qaab manshuur. Mid kasta oo ka siddooyinkii ururiya fudud ku jirase aad cidhiidhi ah ee rays barbar diverging xarunta. By qoqobada dhululubo ku wareegsan saqafka u il iftiinkooduna kordhin in jid toosan. alwaaxdii saqafka haysay Color, tiradooda, bareeg time iyaga u dhexeeya koobnaan minaarad far u gaar ah gaar ah. kooban oo ka mid ah sifooyinka oo ka mid ah lighthouses kala duwan ku lahaa doonniyo guddiga, oo waa badmaax iyada bartay tusaaale ku hortooda ku.

gashto Fresnel rakibay in lighthouses, waa tallaabo muhiim ah oo ku qalabeysey ilo iftiin xoog badan. Kuwani gashto farcan adag ka dhigtay in ay suurto gal ah in ay kor u fiirsashada ee adag ilaa 80 000 cd.

The guryaha indhaha ee lenses waxaa sidoo kale loo isticmaalaa in duurka ku of multimedia. Sidaas daraaddeed, oo ay DNP, soo saare ugu weyn ee screens qiyaas farsmada heerka sare ah, iyadoo ay ku saleysan gashto waa screens supernovaer.
