Izincazelo zokusebenza kwesihlungi ziyizincazelo ezidingekayo zokusebenza kwesihlungi ngolimi olungaqondwa kalula ngabaklami bezinhlelo, abasebenzisi, abakhiqizi besihlungi, njll. Ngezinye izikhathi umenzi wesihlungi ubhala izincazelo ngokusekelwe ekusebenzeni okufinyelelekayo kwesihlungi. Ngezinye izikhathi zibhalwa umenzi wesihlungi ngokusekelwe ekusebenzeni okufinyelelekayo kwesihlungi, kungaba ngumsebenzisi, noma ikhathalogi yomkhiqizo ejwayelekile engasetshenziswanga ngokucacile, yokugcina esingeke siyixoxe lapha. Ezimweni eziningi, izincazelo zokusebenza zivame ukubhalwa ngumklami wesistimu.
Ukuze kutholakale ukusebenza okufiswayo ohlelweni, umklami uchaza ukusebenza okudingekayo kwesihlungi ngesilinganiso. Ekubhaleni isilinganiso esinjalo, umbuzo wokuqala okumele uphendulwe uthi: Isihlungi sisetshenziselwani? Inhloso yesihlungi kumele ichazwe ngokucacile nangokunembile, futhi lokhu kuzoba yisisekelo sokubhala. Ayikho indlela ehlelekile yokucacisa imininingwane yokusebenza. Ngezinye izikhathi ukusebenza kwesistimu lapho isihlungi sisetshenziswa khona kufanele kube sezingeni elithile, ngaphandle kwalokho ngeke kube nokugxila encazelweni eyengeziwe. Izidingo zokusebenza zesihlungi kufanele zinqunywe kalula, kodwa lokhu ngokuvamile akuwona umsebenzi olula. Azikho izidingo eziphelele zokusebenza; ukusebenza kufanele kube phezulu ngangokunokwenzeka ubunzima noma intengo engenzeka. Kulesi simo, uhlelo lusebenzisa izihlungi zokusebenza okuhlukile, futhi ukusebenza kumele kulinganiswe nezindleko zalo, ubunzima, kanye nekhono lokwenza izahlulelo ngalokho okunengqondo. Isilinganiso sokugcina sizoba ukuvumelana phakathi kwalokho okudingekayo nalokho okufinyelelekayo. Lokhu kuvame ukudinga ukufakwa kolwazi oluningi lokuklama nokukhiqiza, kanye nokuxhumana okuseduze phakathi komsebenzisi nomenzi. Kubalulekile ukukhumbula ukuthi imininingwane engazanelisi izinhlelo zokusebenza ezisebenzayo imane nje iyisithakazelo sezemfundo. Isibonelo, ake sicabangele kafushane inkinga: indlela yokuthola umugqa we-spectral ku-spectrum eqhubekayo. Ngokusobala, kudingeka isihlungi se-narrowband, kodwa yimuphi umkhawulokudonsa kanye nohlobo luni lwesihlungi oludingekayo? Amandla omugqa we-spectral odluliselwa yisihlungi azoncika kakhulu ekudluliseleni kwawo okuphezulu (uma sicabanga ukuthi indawo ephezulu yesihlungi ingalungiswa njalo kumugqa we-spectral enkingeni), kuyilapho amandla e-continuum spectrum ezoncika endaweni ephelele engaphansi kwe-transmittance curve, kufaka phakathi indawo ye-wavelength cutoff kude ne-peak. Uma i-passband incane, kulapho umehluko phakathi kwe-harmonic continuum kanye ne-continuous spectrum uphakama, ikakhulukazi njengoba i-passband iba ncane, okuvame ukwandisa i-cutoff. Kodwa-ke, uma i-passband incane, kuzoba kubi kakhulu ukuyikhiqiza, njengoba ukuncishiswa kwe-passband kwandisa ubunzima bokukhiqiza; futhi kuzokwenza isilinganiso se-focal esivumelekile sibe sikhulu, njengoba kwandisa ukuzwela kokungaqoqeki kokukhanya. Iphuzu lokugcina lapha lisho ukuthi ngensimu efanayo yokubuka, i-bandwidth encane yesihlungi kumele yenziwe ibe nkulu, ukuze kusetshenziswe isilinganiso esikhulu se-focal, kodwa lokhu kuzokwandisa ubunzima bokwenziwa kanye nobunzima bohlelo lonke. Enye indlela yokuthuthukisa ukusebenza kwesihlungi ukwandisa ukuthambeka komphetho we-passband kodwa ugcine i-bandwidth efanayo. Isimo se-passband esingunxande sinokuhluka okuphezulu kunesihlungi se-Fabry-Perot esilula esinobubanzi obufanayo, futhi i-passband inenzuzo eyengeziwe yokuthi i-cutoff kude nesiqongo sesihlungi nayo iba nkulu. Ukuchaza lokhu kuthambeka komphetho nge-bandwidth engu-1/10 noma i-bandwidth engu-1/100 kunganqunywa. Futhi, uma umphetho uphakeme, kuba nzima futhi kubiza kakhulu ukuwukhiqiza.
