Sefa mashandiro ekuita zvinotsanangurwa zvinodikanwa zvesefa kuita mumutauro unogona kunzwisiswa zviri nyore nevagadziri vehurongwa, vashandisi, vanogadzira mafirita, nezvimwewo. Dzimwe nguva mugadziri wesefa anonyora zvakatemwa zvichienderana nekuita kunogoneka kwesefa. Dzimwe nguva anonyorwa nemugadziri wesefa zvichibva pane zvinogoneka kuita sefa, ingave yemushandisi, kana yeyakajairwa chigadzirwa catalog isina kunyatso shandiswa, iyo yekupedzisira yatisingazokurukura pano. Muzviitiko zvakawanda, maitiro ekuita anowanzo kunyorwa neanogadzira system.
Kuti uwane kuita kwaunoda kubva kuhurongwa, mugadziri anotsanangura mashandiro anodiwa esefa mune metric. Mukunyora metric yakadai, mubvunzo wekutanga unofanirwa kupindurwa ndewekuti: Sefa inoshandiswa nei? Chinangwa chesefa chinofanira kuve chakajeka uye chakanyatsotsanangurwa, uye ichi chichava hwaro hwekunyora. Iko chaiko hakuna yakarongeka nzira yekutsanangura maitiro ekuita. Dzimwe nguva kuita kwegadziriro iyo sefa inoshandiswa kunofanirwa kunge kune imwe nhanho, zvikasadaro hapazove nekutarisisa mune imwezve rondedzero. Zvinodiwa zvekuita zvesefa zvinofanirwa kutariswa zviri nyore, asi kazhinji kacho harisi basa riri nyore. Hapana mhedziso zvinodiwa pakuita basa; kushanda kunofanirwa kunge kwakakwira sekuoma kana mutengo unogoneka unobvumira. Muchiitiko ichi, sisitimu inoshandisa mafirita ekuita kwakasiyana, uye kuita kunofanirwa kuenzana nemutengo wayo, kuoma, uye kugona kuita mutongo pamusoro pezvinonzwisisika. Iyo metric yekupedzisira ichave kuwirirana pakati pezvinodiwa uye izvo zvinogoneka. Izvi zvinowanzoda kuiswa kwehuwandu hwekugadzira nekugadzira ruzivo, uye kutaurirana kwepedyo pakati pemushandisi nemugadziri. Zvakakosha kuyeuka kuti zvirevo zvisingagutsi mashandisirwo anoshanda zvinongori zvechido chedzidzo. Semuenzaniso, ngatitarisei muchidimbu dambudziko: nzira yekuwana mutsara we spectral mune inoenderera spectrum. Zviripachena, narrowband sefa inodiwa, asi ndeipi bandwidth uye rudzii rwesefa inodiwa? Iyo simba reiyo spectral mutsara inofambiswa nesefa inotsamira zvakanyanya pane yayo yepamusoro transmittance (tichifunga kuti iyo yepamusoro chinzvimbo chesefa inogona kugara ichigadziriswa kune spectral mutsara mudambudziko), nepo simba reinoenderera mberi spectrum rinoenderana nenzvimbo yakazara pazasi peiyo transmittance curve, kusanganisira iyo wavelength cutoff dunhu kure nepamusoro. Iyo yakatetepa bhendi, inokwirisa mutsauko pakati peharmonic inoenderera uye inoenderera spectrum, kunyanya sezvo passband inova diki, iyo inowanzo wedzera cutoff. Zvisinei, iyo yakamanikana passband, iyo inodhura zvikuru ichava yekugadzira, sezvo kuderedzwa kwepasisi kunowedzera kuoma kwekugadzira; uye ichaitawo kuti inobvumirwa focal ratio ive yakakura, sezvo ichiwedzera kunzwisiswa kune optical noncollimation. Mhedziso yekupedzisira pano inoreva kuti kune imwe nzvimbo yekuona, iyo yakaderera bandwidth yefirita inofanira kuitwa yakakura, kuitira kuti chiyero chikuru chekutarisa chinogona kushandiswa, asi izvi zvichawedzera kuoma kwekugadzira uye kuoma kwehurongwa hwose. Imwe nzira yekuvandudza mashandiro esefa ndeyekuwedzera kumucheto kwepassband asi uchiramba uchichengetedza bandwidth yakafanana. Iyo rectangular passband chimiro ine musiyano wepamusoro pane yakapfava Fabry-Perot sefa ine hafu-upamhi, uye iyo passband ine yakawedzera mukana wekuti iyo cutoff iri kure nesefa peak zvakare inova yakakura. Kutsanangura kutsetseka uku ne1/10 bandwidth kana 1/100 bandwidth inogona kutsanangurwa. Zvakare, kukwidza kwacho, kunowedzera kuoma uye kudhura kwairi kugadzira.
