Umshayeli we-LED womshini wokubona amandla aphezulu

Isistimu yombono womshini isebenzisa ukukhanya okufushane okunamandla okufushane kakhulu ukukhiqiza izithombe zejubane eliphezulu zezinhlelo zokusebenza ezihlukahlukene zokucubungula idatha. Isibonelo, ibhande lokuthutha elihamba ngokushesha lenza ukulebula okusheshayo nokutholwa kokukhubazeka ngesistimu yokubona umshini. I-infrared ne-laserI-LEDamalambu ama-flash avame ukusetshenziswa ekuboneni umshini webanga elifushane kanye nokunyakaza. Isistimu yokuphepha ithumela isivinini esikhulu, esingabonakaliI-flash ye-LEDukuthola ukunyakaza, ukuthwebula nokugcina izithombe zokuphepha.

Inselele yazo zonke lezi zinhlelo ukukhiqiza amaza amaza ekhamera aholayo aphezulu kakhulu amanje nawesikhathi esifushane (microsecond) angase asakazeke isikhathi eside, afana no-100 ms kuya ngaphezu kwesekhondi elingu-1. Akulula ukukhiqiza igagasi lesikwele le-LED lesikhathi esifushane elinesikhawu eside. Lapho ukushayela kwamanje kwe-LED (nomaIntambo ye-LED) ikhuphukela ngaphezu kuka-1 A futhi i-LED ngesikhathi ifinyezwa kuma-microseconds ambalwa, inselele iba nzima kakhulu. Abashayeli abaningi be-LED abanekhono le-PWM elinesivinini esikhulu bangase bangakwazi ukucubungula ngokuphumelelayo izinga eliphezulu ngesikhathi eside kanye nesikhathi esifushane ngaphandle kokunciphisa ikhwalithi yegagasi yesikwele edingekayo ukuze kucutshungulwe kahle izithombe ezinesivinini esikhulu.
