Intangiriro ku bipimo by'imikorere ya firiti - Igice cya 1

Ibisobanuro by'imikorere y'urufunguzo ni ibisobanuro by'ingenzi ku mikorere y'urufunguzo mu rurimi rushobora kumvikana byoroshye n'abashushanya sisitemu, abakoresha, abakora urufunguzo, n'ibindi. Hari igihe uruganda rukora urufunguzo rwandika ibisobanuro bishingiye ku mikorere ishoboka y'urufunguzo. Hari igihe byandikwa n'uruganda rukora urufunguzo bishingiye ku mikorere ishoboka y'urufunguzo, haba ku mukoresha, cyangwa ku katalogu y'ibicuruzwa bisanzwe idakoreshwa mu buryo bweruye, iya nyuma tutazayivugaho hano. Kenshi na kenshi, ibisobanuro by'imikorere akenshi byanditswe n'uruganda rukora sisitemu.

Kugira ngo haboneke imikorere ikenewe muri sisitemu, umuhanga mu bya firime asobanura imikorere isabwa ya firime mu gipimo. Mu kwandika ikigereranyo nk'iki, ikibazo cya mbere kigomba gusubizwa ni iki: Iyi firime ikoreshwa iki? Intego ya firime igomba kuba isobanutse neza kandi neza, kandi iyi ni yo izaba ishingiro ry'inyandiko. Nta buryo buhamye bwo kugaragaza amakuru arambuye ku mikorere. Hari igihe imikorere ya sisitemu ikoreshwamo firime igomba kuba iri ku rwego runaka, bitabaye ibyo nta kwibanda ku bisobanuro birambuye bizabaho. Ibisabwa ku mikorere ya firime bigomba kugenwa byoroshye, ariko akenshi si akazi koroshye. Nta bisabwa byimazeyo ku mikorere; imikorere igomba kuba iri hejuru uko igiciro cyangwa igiciro gishoboka kibikwemerera. Muri iki gihe, sisitemu ikoresha firime z'imikorere itandukanye, kandi imikorere igomba kuringanizwa n'igiciro cyayo, imiterere yayo, n'ubushobozi bwo gufata ibyemezo ku bifatika. Igipimo cya nyuma kizaba ubwumvikane hagati y'ibikenewe n'ibishoboka kugerwaho. Ibi akenshi bisaba ko habaho amakuru menshi y'igishushanyo n'inganda, hamwe n'itumanaho rya hafi hagati y'umukoresha n'uwakoze. Ni ngombwa kwibuka ko ibisobanuro bidahuye n'ikoreshwa ry'ibintu mu buryo bufatika ari inyungu gusa mu by'ubushakashatsi. Urugero, reka turebere hamwe muri make ikibazo: uburyo bwo kubona umurongo wa spectral muri spectrum ihoraho. Birumvikana ko hakenewe filter ya narrowband, ariko se ni ubuhe buryo bw'ingufu n'ubwoko bw'filter bukenewe? Ingufu z'umurongo wa spectral woherezwa na filter zizaterwa ahanini n'uburyo bwo kohereza peak yayo (dufashe ko aho peak ya filter iherereye hashobora guhindurwa ku murongo wa spectral uri mu kibazo), mu gihe ingufu za spectrum ya continuum zizaterwa n'agace kose kari munsi y'umurongo wa transmittance, harimo n'agace k'uburebure bw'umuraba kure y'umutwe. Uko passband igenda iba nto, ni ko itandukaniro riri hagati ya harmonic continuum na spectrum ihoraho riba riri hejuru, cyane cyane ko passband igenda iba nto, ibyo bikaba byongera quartoff. Ariko, uko passband igenda iba nto, ni ko ihenda cyane kuyikora, kuko kugabanya passband byongera ingorane mu gukora; kandi bizatuma ikigereranyo cyemewe cy'ifatizo kirushaho kuba kinini, kuko byongera ubushobozi bwo kumva ko nta collimation y'amajwi igaragara. Ingingo ya nyuma hano bivuze ko ku buso bumwe, umurambararo muto w'urufunguzo ugomba kuba munini, kugira ngo hakoreshwe ikigereranyo kinini cy'ifatizo, ariko ibi byongera ingorane zo gukora no gukomera kwa sisitemu yose. Uburyo bumwe bwo kunoza imikorere ya rufunguzo ni ukongera ubujyakuzimu bw'inkombe z'urufunguzo ariko ugakomeza kugumana umurambararo umwe. Imiterere y'urufunguzo rw'urukiramende rufite itandukaniro rinini kurusha urufunguzo rworoshye rwa Fabry-Perot rufite ubugari bumwe, kandi urufunguzo rw'urukiramende rufite inyungu yiyongereyeho ko aho ruca kure y'agasongero k'urufunguzo na ho rurushaho kuba runini. Gusobanura ubu burebure bw'inkombe hakoreshejwe umurambararo wa 1/10 cyangwa umurambararo wa 1/100 bishobora kumenyekana. Nanone, uko urujya n'uruza rurushaho kuba rurerure, ni ko bigorana kandi bihenze kubikora.
