Ka'ida da rarraba hazo
(1) ka'ida
Ka'idar hazo ana kiranta Sagnac sakamako a kimiyyar lissafi. A cikin rufaffiyar hanyar haske, za a tsoma baki ɓangarorin haske biyu daga tushen haske ɗaya lokacin da aka haɗa su zuwa wurin ganowa iri ɗaya. Idan hanyar haske da aka rufe tana da juyawa dangane da sararin da ba a iya aiki ba, igiyar da ke yaduwa a cikin hanyoyi masu kyau da kuma mummunan za su haifar da bambancin hanyar haske, wanda ya dace da saurin kusurwar juyawa na sama. Ana ƙididdige saurin jujjuyawar kusurwa ta amfani da bambancin lokaci da aka auna ta hanyar gano hasken hoto.
Daga dabarar, tsawon tsayin fiber ɗin, mafi girman radius na tafiya na gani, gajeriyar raƙuman gani. Mafi shaharar tasirin kutse shine. Don haka mafi mahimmancin ƙarar hazo, mafi girman daidaito. Sakamakon Sagnac shine ainihin tasiri mai mahimmanci, wanda yake da mahimmanci ga zane na danshi.
Ka'idar hazo ita ce, ana fitar da hasken haske daga bututun photoelectric kuma ya wuce ta ma'aurata (ƙarshen ɗaya ya shiga tashoshi uku). Biyu suna shigar da zoben ta hanyoyi daban-daban ta cikin zoben sannan su dawo kusa da da'ira ɗaya don madaidaicin matsayi. Hasken da ya dawo yana komawa kan LED kuma yana gano ƙarfin ta cikin LED. Ka'idar hazo tana da sauƙi, amma abu mafi mahimmanci shine yadda za a kawar da abubuwan da suka shafi hanyar gani na katako guda biyu - matsala mai mahimmanci don zama hazo.
Ka'idar fiber optic gyroscope
(2) rarrabawa
Bisa ga ka'idar aiki, fiber na gani gyroscopes za a iya raba zuwa interferometric fiber optic gyroscope (I-FOG), resonant fiber optic gyroscope (R-FOG), da kuma karfafa Brillouin watsawa fiber optic gyroscope (B-FOG). A halin yanzu, mafi balagagge fiber optic gyroscope shi ne interferometric fiber optic gyroscope (na farko ƙarni fiber optic gyroscope), wanda aka yi amfani da ko'ina. Yana amfani da na'urar fiber mai juyawa da yawa don haɓaka tasirin Sagnac. A gefe guda kuma, interferometer na katako na katako guda biyu wanda ya ƙunshi nau'i mai nau'i-nau'i mai nau'i-nau'i na fiber na iya samar da daidaitattun daidaito, wanda zai sa tsarin duka ya fi rikitarwa.
Dangane da nau'in madauki, ana iya raba hazo zuwa hazo mai buɗewa da rufaffiyar madauki FOG. Gyroscope na fiber na gani mai buɗewa (Ogg) yana da fa'idodin tsari mai sauƙi, ƙarancin farashi, babban aminci, da ƙarancin amfani da wutar lantarki. A gefe guda, rashin amfanin Ogg shine rashin daidaituwar shigarwa-fitarwa da ƙarami mai ƙarfi. Saboda haka, ana amfani da shi musamman azaman firikwensin kusurwa. Tushen tsarin IFOG mai buɗewa shine interferometer mai tsayi biyu. Sakamakon haka, ana amfani da shi da farko a cikin yanayin rashin daidaituwa da ƙananan ƙara.
