Matakan aiki nana'urar daidaita acousto-optical free space
Wurin kyautamai daidaita acousto-opticshigarwa da fitar da hasken ta hanyar ramukan haske masu buɗewa, suna buƙatar daidaito daidai da daidaitawar kusurwar Bragg tare da firam ɗin daidaitawa mai girma uku. Idan aka kwatanta da jerin haɗin zare, jerin sararin samaniya kyauta yana buƙatar ƙarin matakan daidaita hanyar gani, amma yana da fa'idodi kamar hanyoyin gani masu sassauƙa da lura da wuraren diffraction mai sauƙi.
1. Matakan shigarwa da daidaitawa na duniya don jerin modulator na acousto-optic na sarari kyauta
Shigarwa da daidaitawar na'urar acousto-optic modulator ta sararin samaniya kyauta matakai ne na aiki gama gari ga samfura biyu, kamar haka:
Mataki na 1: Bayan an haɗa dukkan na'urori da da'irori na waje, a gyara na'urar acousto-optic a kan firam ɗin daidaitawa mai girma uku, a daidaita tsayin na'urar acousto-optic sama da ƙasa don ba da damar hasken laser ya ratsa ta wurin da ya dace na na'urar acousto-optic. Lura: Matsayin haske mafi kyau yana tsakiyar kauri na lu'ulu'u, kuma nesa da 1.5mm daga wutar lantarki ta zinariya kafin da bayan dannawa.
Mataki na 2: Kunna wutar lantarki ta 24V sannan a ɗora siginar (ana ba da shawarar a ajiye siginar a 5V lokacin da ake gyara ƙarfin diffraction, don wutar lantarki ta ci gaba da aiki). Daidaita kusurwar Bragg nana'urar acousto-opticalhagu da dama don cimma mafi girman ƙarfin diffraction na farko.
Mataki na 3: Bayan daidaita hasken diffraction na farko na na'urar acousto-optic, ana iya loda kowace sigina bisa ga buƙatun gwaji.
Nau'in 2 0~5V (sarari kyauta)
2.1 Bayanin Siginar Sauyawa
Ana amfani da tashar jiragen ruwa ta "0-5V" don loda siginar sarrafawa kuma siginar analog ce ta 0-5V. Kashe lokacin da ƙarfin shigarwar ya kai 0V, kuma ƙarfin fitarwa na RF ya kai matsakaicinsa lokacin da ƙarfin shigarwar ya kai 5V. Hanyar daidaitawa ta wannan samfurin ta yi daidai da nau'in analog na zare da aka haɗa da "nau'in analog na 0-5V", amma tsarin hanyar gani ya bambanta, yana buƙatar ƙarin shigarwa da matakan daidaitawa.
2.2 Hanyar haɗi
"RF" na wutar lantarki mai tuƙi shine tashar fitarwa ta wutar lantarki ta RF. Da fatan za a haɗa shi da layin siginar BNC mai dacewa, kuma ɗayan ƙarshen layin siginar ya kamata a haɗa shi kai tsaye zuwa na'urar sauti da haske tare da BNC. Lura cewa wannan samfurin yana amfani da hanyar sadarwa ta BNC, wanda ya bambanta da hanyar sadarwa ta SMA na yawancin samfuran haɗin fiber.
2.3 Tsarin iko
Da fatan za a yi amfani da sukudireba na Phillips don juya ƙaramin maɓallin ramin da ke gefe. Ƙarfin juyawa yana ƙaruwa a gefen agogo, yayin da ƙarfin juyawar da ke akasin agogo ke raguwa. Lura cewa maɓallin daidaitawar wutar lantarki na wannan samfurin yana cikin ƙaramin rami a gefe, wanda ya bambanta da tashar "modulation na amplitude" na sauran samfuran.
3 Nau'in mai amfani da wutar lantarki mai girma (sarari kyauta)
3.1 Bayanin Siginar Sauyawa
Ana amfani da tashar 'modulation' don loda siginar sarrafawa kuma siginar dijital ce ta TTL ta yau da kullun. Wutar lantarki tana gudana a babban mataki, kuma dole ne a yi amfani da ƙarfin lantarki na 5V a tashar "modulation" don samar da fitowar wutar lantarki ta RF. Lokacin da tashar modulation take a matakin ƙasa, ana kashe fitowar RF. Halayen daidaitawa na wannan samfurin iri ɗaya ne da "nau'in watsawa mai girma" na haɗin fiber, amma tsarin hanyar gani ya bambanta, yana buƙatar ƙarin matakan shigarwa da daidaitawa. Lura: Wutar lantarki tana gudana a babban mataki, kuma dole ne a yi amfani da ƙarfin lantarki na 5V a ƙarshen "modulation" don samar da fitowar wutar lantarki ta RF.
3.2 Tsarin iko
Da fatan za a yi amfani da sukudireba na Phillips don juya ƙaramin maɓalli a cikin ƙarshen "modulation na amplitude". Ƙarfin juyawa yana ƙaruwa a hannun agogo, yayin da ƙarfin juyawa na akasin agogo yana raguwa. Lura cewa alkiblar daidaita wutar lantarki ta wannan samfurin ta saba da nau'in haɗin fiber mai babban matakin watsawa!
