Fresnel lens ukusuka beacons kwiindawo multimedia

Kwixesha elidlulileyo, indlela ukuya elunxwemeni oomatiloshe yaba ingxenye eyingozi yohambo lwabo. Ngenxa yemozulu embi okanye ndixakene namawa sonxweme kunokubangela konakele. oomatiloshe wophula iinqanawa best Isakhiwo olwandle yelo xesha. Kangangexesha elide kwi ezincotsheni zazo ngamandla nje umlilo, kamva umthombo ukukhanya izibane zeparafini de umbane waqalisa ukusetyenziswa. Ngenkulungwane XIX, ukukhanya, ubomi ugcino, iba lens Fresnel eyenza Ukukhanya iinqanawa kakhulu umxhelo kunye ubonakale kude.

lens entsonkothileyo Inxenye wenziwa ngu Augustin Fresnel, yamachiza French, umseki imfundiso otshangatshangiswayo ukukhanya. Fresnel lens sakhiwa ubukhulu encinane amakhonkco concentric ngamnye ezikufutshane omnye komnye nokwakha itankana kunye njengomthombo ukukhanya. Le amakhonkco abe ukuma nonxantathu. Ngalinye emakhonkcweni ziqokelela ukukhanya umqadi ube mnye imxinwa reyi ngaxeshanye yehlukana ukusuka kwiziko. Xa kokutshintsha isilinda ngeenxa imiqadi umthombo ukukhanya ukukhanya uqhebeke kunina. imiqadi Umbala, ngangenani lazo, ixesha lekhefu phakathi kwabo kube umbhalo unique CTLI okhethekileyo. Isishwankathelo iimpawu iinqanawa ezahlukeneyo saba phezu iinqanawa ebhodini, kwaye ukuba oomatiloshe bafunda esiphezu phambi kwabo.

lens Fresnel efakwe iinqanawa, linyathelo elibalulekileyo ngokubaxhobisa kunye imithombo ukukhanya enamandla.

Ukulungiselela le njongo kuyimfuneko njengenxenye enombala elimlinganiselo enkulu, umhlaba ophantsi kweempembelelo womxhuzulane yayo akwazi kugqabhuka. Ngoko ke, sebenzisa ezininzi yezibuko phakathi, ugqaliselo ngamnye kubo yaba lantern enye. Esi sigqibo ke kwandim.

I Fresnel lens edityanisiweyo zanceda ukufezekisa ukwanda ngamandla ukukhanya, lo xiyimiso xa nkongomiso lowu. Indibano izinto ngamnye enombala ayibonisi ukukhanya, yaye wayesebenza ekukhanyeni, olujikelezayo ngeenxa ibonakala yi kumthombo ukukhanya ngamandla rhoqo kuzo zonke iindlela.

Ekubeni isakhiwo Fresnel na isixhobo nanto esisetyenzisiweyo hayi kuphela River buoys kunye Nezinto. Xa lens yokuqala Fresnel esenziwe iglasi izibane ezahlukeneyo kweesiginali, iirobhothi, izibane isithuthi, iiprojektha iindawo zokufundela. Ke magnifiers wadalwa ngohlobo imigca ezenziwe seplastikhi esitransparenti, kunye vee zokuqhubela setyhula, iyileyo ibe kwimilo elincinane thunzi, kodwa jikelele zaba lens ukubuthwa. Ilens ngenxa isetyenziswa iglasi ukuba into enkulu efana kwekhamera, ukudala umfanekiso zocaphulo.

Ekuhambeni kwexesha, kwenkululeko the Fresnel lens iye yandiswa kakhulu. Oku kuquka uphuhliso yokuthathwa, izixhobo ezahlukeneyo izibane, iinkqubo zokhuseleko, izixhobo esweni, amandla concentrator ngenxa solar, nezipili asetyenziswa yerediyo. Iimpawu nabizayo lens nazo kusetyenziswa kwinkalo multimedia. Ngoko ke, i DNP, umvelisi likhulu ophezulu-obuchwepheshe screens kwelivi, ngokusekelwe lens ezi izikrini eqhumayo. Xa lingena yesimo screen lisetyenziswa nje kuphela Fresnel lens, kodwa ezinye zobuchwepheshe enombala, nto leyo evumela ukuba afumane iindlela ukubonisa ezizodwa.

Fresnel lens iye sisixhobo ngemiba yezemfundo, kwepensile wadlala indima ebalulekileyo endle ubugcisa.
