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 iifomayimu 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 ngakumbi.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.
