Umqhubi we-LED wokukhanya kombono womatshini wamandla aphezulu

Inkqubo yombono womatshini isebenzisa ukukhanya okufutshane kakhulu okufutshane ukuvelisa imifanekiso enesantya esiphezulu kwiinkqubo ezahlukeneyo zokucwangcisa idatha. Umzekelo, ibhanti lokuhambisa elihamba ngokukhawuleza lenza iilebhile ngokukhawuleza kunye nokufumanisa isiphene ngenkqubo yokubona umatshini. I-infrared kunye ne-laserI-LEDIzibane ezidanyazayo ziqhele ukusetyenziswa kuluhlu olufutshane kunye nombono womatshini wokubona intshukumo. Inkqubo yokhuseleko ithumela isantya esiphezulu, ingabonakaliIsibane se-LEDukubona intshukumo, ukubamba kunye nokugcina imifanekiso yokhuseleko.

Umceli mngeni kuzo zonke ezi nkqubo kukuvelisa iifomu zekhamera ezikhokelayo eziphezulu kakhulu zangoku kunye nexesha elifutshane (microsecond) ezinokusasazeka kwixesha elide, njenge-100 ms ukuya ngaphezu kwe-1 s. Akukho lula ukuvelisa i-LED yexesha elifutshane le-square wave kunye nekhefu elide. Xa i-LED iqhuba ngoku (okanyeUmtya we-LED) iphakama ngaphezu kwe-1 A kunye ne-LED ngexesha lifutshane kwi-microseconds ezimbalwa, umngeni uba nzima. Abaqhubi abaninzi be-LED abanesantya esiphezulu se-PWM abanakukwazi ukuqhubela phambili ngokufanelekileyo ngoku kunye nexesha elide kunye nexesha elifutshane ngaphandle kokunciphisa umgangatho we-square wave ofunekayo ukuqhutyelwa ngokufanelekileyo kwemifanekiso enesantya esiphezulu.
