Inta lagu guda jiro habka farsamaynta laysarka, waxaan inta badan aragnaa halbeegga "PWM", markaa maxay ka dhigan tahay, aynu maanta eegno.
PWM waa soo gaabinta "Pulse Width Modulation", oo loo yaqaan "pulse width modulation" ama "modulation", waa farsamo aad waxtar u leh oo loo isticmaalo soosaarka dhijitaalka ah ee microprocessor si loo xakameeyo wareegyada analoogga ah.
Habka wax soo saarka ee laysarka inta badan waxaa ka mid ah laba nooc: hab joogto ah iyo habka garaaca wadnaha.Habka joogtada ah waa toogashada joogtada ah ee laysarka;Habka garaaca wadnaha waa in la sii daayo laser isku mar wakhti kasta oo kale.Tusaalaha fudud, sida tooshka ifaya: daarida daaran ma damin waa hab joogto ah;Daarida daarta isla markiiba ka dibna dami waa in la soo daayo garaaca wadnaha, habka soo noqnoqda iyo daminta waa habka garaaca wadnaha.Sidoo kale, marka tooshka lagu beddelo laysarka, habka garaaca garaaca waa inuu ku celceliyaa habka daminta iyo daminta iftiinka si joogto ah.
Habka ugu toosan ee loo dhaliyo leysarka garaaca wadnaha waa in lagu daro modulator leysarka CW si loo habeeyo leysarka CW si loo helo wax soo saarka garaaca wadnaha.PWM (Modulation Width Width Pulse) waa in la hagaajiyo ballaca garaaca wadnaha iyadoo la hagaajinayo wareegga shaqada.
Marka la hagaajinayo halbeegyada habka goynta laysarka, garaaca garaaca iyo wareegyada waajibaadka ayaa inta badan la isticmaalaa, iyo hawl wadeeno badan oo aan aqoon u lahayn habka goynta laysarka ayaa laga yaabaa inay fahmaan doorka labadan cabbir, ka dibna ku siiyaan hordhac faahfaahsan.
1Muddada
Calaamadu waxay ka socotaa sare ilaa hoos waxayna dib ugu noqotaa sare ilaa hal usbuuc
2Heerka soo noqnoqda garaaca wadnaha
Immisa wareeg oo PWM ah ayaa ku jira 1 ilbiriqsi
3Wareega shaqada garaaca wadnaha
Tusaalaha saamiga wakhtiga heerka sare iyo wakhtiga wareegtada oo dhan ee meerto
4Waqtiga garaaca wadnaha
Muddada wakhtiga lagu qaato wareeg
5Ballaca garaaca
Waqtiga loo isticmaalo in muddo ah oo heer sare ah
6Heerka awoodda ugu sarreysa
Soosaarka tamarta degdegga ah ee laysarka gudaha hal ballac oo garaaca wadnaha ah
7Celceliska heerka shaqada
Qadarka tamarta laysarka ka soo baxa wareegga soo noqnoqda
Caadi ahaan, marka aan wax ka beddelno laysarka ee habka laysarka hagaajinta, awoodda ugu sarreysa, inta jeer ee garaaca wadnaha iyo wareegga waajibaadka ayaa la dejiyaa.Marka xigta, aan isticmaalno tusaale si aan u muujinno sida loo xisaabiyo cabbirrada PWM.
Awoodda ugu sarreysa ee laysarka, wareegga waajibaadka garaaca wadnaha ayaa kordha, tamarta garaaca garaaca wadnaha kasta ayaa kor u qaadi doonta si waafaqsan, taas oo kordhin doonta awoodda wax-qabadka ee jihada dhumucda saxanka.Haddii wareegga waajibaadka garaaca wadnaha la yareeyo, tamarta garaaca wadnaha kasta waa iftiin, taas oo ka caawisaa in ay yareeyaan khasaaraha xad-dhaaf ah iyo fusing.
Habka birta, tamarta laysarka ayaa loo isticmaalaa, iyo haddii ay dhacdo awoodda laser joogto ah, inta jeer ee sarreeya, tamarta yar ee laser kasta, sidaas darteed waxaan u baahanahay inaan ogaano inta jeer ee ku habboon iyadoo loo eegayo xawaaraha farsamaynta. marka tamarta laysarka ay ku filan tahay inay dhalaaliso birta.
Laser GW oo ku salaysan 976nm tignoolajiyada bamka ee alaabta laser fiber joogto ah, oo leh hufnaan koronto-optical beddelka sare, tayada wax soo saarka wanaagsan, inta jeer modulation ugu badnaan ilaa 50kHz, si ballaaran loo isticmaalo jarida, alxanka, nadiifinta, cladding iyo wax soo saarka wax soo saarka.
