Makina owonera makina amagwiritsa ntchito kuwala kwamphamvu kwakanthawi kochepa kwambiri kuti apange zithunzi zothamanga kwambiri pazogwiritsa ntchito zosiyanasiyana. Mwachitsanzo, lamba wonyamulira woyenda mwachangu amalemba zilembo mwachangu ndikuzindikira zolakwika kudzera pamakina owonera. Infrared ndi laserLEDnyali zowunikira zimagwiritsidwa ntchito kwambiri pamakina afupiafupi komanso ozindikira kuyenda. Chitetezo chimatumiza mwachangu kwambiri, osawonekaKuwala kwa LEDkuti muzindikire zoyenda, kujambula ndi kusunga zithunzi zachitetezo.
Chovuta pa machitidwe onsewa ndikupanga mawonekedwe apamwamba kwambiri amakono komanso anthawi yochepa (microsecond) omwe amatsogolera makamera omwe amatha kufalikira kwa nthawi yayitali, monga 100 ms mpaka 1 s. Sikophweka kupanga mawonekedwe ang'onoang'ono a LED flash square ndi nthawi yayitali. Pamene kuyendetsa panopa kwa LED (kapenaChingwe cha LED) imakwera kuposa 1 A ndipo LED pa nthawi imafupikitsidwa mpaka ma microseconds ochepa, vutolo limakhala lovuta kwambiri. Madalaivala ambiri a LED omwe ali ndi mphamvu yothamanga kwambiri ya PWM sangathe kuyendetsa bwino zamakono ndi nthawi yayitali komanso nthawi yochepa popanda kuchepetsa mawonekedwe a square wave omwe amafunikira kuti akonze bwino zithunzi zothamanga kwambiri.
