Na farko, Tsarin Ciki da Tsarin Waje
Dangane da dangantakar da ke tsakanin modulator da laser, an gano cewa na'urar tana aiki da kyau.gyaran laserza a iya raba su zuwa tsarin daidaitawa na ciki da tsarin daidaitawa na waje.
01 gyaran ciki
Ana gudanar da siginar daidaitawa ne a cikin tsarin juyawar laser, wato, ana canza sigogin juyawar laser bisa ga dokar siginar daidaitawa, don canza halayen fitowar laser da cimma daidaito.
(1) A sarrafa tushen famfon laser kai tsaye don cimma daidaiton ƙarfin laser na fitarwa da kuma ko akwai, ta yadda wutar lantarki za ta iya sarrafa shi.
(2) An sanya sinadarin daidaitawa a cikin resonator, kuma canjin halayen jiki na bangaren daidaitawa ana sarrafa shi ta hanyar siginar don canza sigogin resonator, don haka yana canza halayen fitarwa na laser.
02 Daidaitawar waje
Daidaitawar waje ita ce rabuwar samar da laser da daidaitawa. Yana nufin ɗaukar siginar da aka daidaita bayan ƙirƙirar laser, wato, an sanya modulator a cikin hanyar gani a wajen resonator na laser.
Ana ƙara ƙarfin siginar daidaitawa zuwa na'urar don yin wasu halaye na zahiri na yanayin modulator, kuma lokacin da laser ya ratsa ta cikinsa, ana daidaita wasu sigogi na raƙuman haske, don haka ana ɗaukar bayanan da za a aika. Saboda haka, daidaitawar waje ba don canza sigogin laser ba ne, amma don canza sigogin laser fitarwa, kamar ƙarfi, mita, da sauransu.
Na biyu,na'urar sarrafa laserrarrabuwa
Dangane da tsarin aiki na modulator, ana iya rarraba shi zuwa cikindaidaitawar lantarki, daidaitawar acoustooptic, daidaitawar magneto-optic da kuma daidaitawa kai tsaye.
01 Daidaitawa kai tsaye
Tukin da ke tuƙi naLaser na semiconductorko kuma diode mai fitar da haske ana daidaita shi kai tsaye ta hanyar siginar lantarki, don haka hasken fitarwa yana daidaitawa tare da canjin siginar lantarki.
(1) Tsarin TTL a cikin daidaitawa kai tsaye
Ana ƙara siginar dijital ta TTL zuwa ga wutar lantarki ta laser, ta yadda za a iya sarrafa wutar lantarki ta hanyar siginar waje, sannan a iya sarrafa mitar fitarwa ta laser.
(2) Daidaitawar Analog a cikin daidaitawa kai tsaye
Baya ga siginar analog ta wutar lantarki ta laser (girman ƙasa da 5V canjin siginar canji ba bisa ƙa'ida ba), zai iya sa shigarwar siginar waje ta bambanta da ƙarfin lantarki daban-daban na laser, sannan kuma sarrafa ƙarfin laser na fitarwa.
02 Daidaitawar na'urar lantarki
Ana kiran gyaran lantarki ta amfani da tasirin lantarki. Tushen zahiri na gyaran lantarki shine tasirin lantarki, wato, a ƙarƙashin aikin filin lantarki da aka yi amfani da shi, ma'aunin haske na wasu lu'ulu'u zai canza, kuma lokacin da hasken ya ratsa ta wannan hanyar, halayen watsawarsa za su shafi kuma su canza.
03 Daidaita Acousto-optic
Tushen zahiri na daidaitawar acousto-optic shine tasirin acousto-optic, wanda ke nufin abin da ke faruwa cewa raƙuman haske suna yaɗuwa ko warwatse ta hanyar filin raƙuman allahntaka lokacin da suke yaɗuwa a cikin matsakaici. Lokacin da ma'aunin haske na matsakaici ke canzawa lokaci-lokaci don samar da grating na ma'aunin haske, diffraction zai faru lokacin da raƙuman haske ke yaɗuwa a cikin matsakaici, kuma ƙarfi, mita da alkiblar hasken diffractive zai canza tare da canjin filin raƙuman da aka samar.
Daidaitawar Acousto-optic tsari ne na zahiri wanda ke amfani da tasirin acousto-optic don loda bayanai akan mai ɗaukar mitar gani. Siginar da aka daidaita ana aiki da ita akan mai canza sauti na lantarki a cikin siginar lantarki (modulation amplitude), kuma siginar lantarki mai dacewa ana canza ta zuwa filin ultrasonic. Lokacin da raƙuman haske suka ratsa ta tsakiyar acousto-optic, mai ɗaukar sauti na gani ana daidaita shi kuma ya zama raƙuman ruwa mai ƙarfi wanda ke "ɗaukar" bayanai.
04 Daidaitawar Magneto-optical
Daidaitawar Magneto-optic aikace-aikace ne na tasirin juyawar gani na lantarki na Faraday. Lokacin da raƙuman haske ke yaɗuwa ta cikin matsakaiciyar magneto-optical a layi ɗaya da alkiblar filin maganadisu, abin da ke faruwa na juyawar jirgin sama na hasken da aka raba shi da layi ana kiransa juyawar maganadisu.
Ana amfani da filin maganadisu mai ɗorewa a kan matsakaici don cimma cikar maganadisu. Alkiblar filin maganadisu na da'irar yana cikin alkiblar axial na matsakaici, kuma juyawar Faraday ya dogara ne akan filin maganadisu na axial current. Saboda haka, ta hanyar sarrafa kwararar na'urar mai yawan mita da canza ƙarfin filin maganadisu na siginar axial, ana iya sarrafa kusurwar juyawar jirgin saman girgizar gani, don haka girman haske ta hanyar polarizer yana canzawa tare da canjin kusurwar θ, don cimma daidaito.
