1. Sebenzisa ubude bokugxila ukuze ushayele endaweni ethile yokubuka: Ubude bokugxila ngakunye bunobude obuthile.Uma ubude obaliwe bungalungile, umphumela oqoshiwe ngeke ufane.
2. Ibhokisi libekwe endaweni ezinzile ukuze i-galvanometer, isibuko sensimu kanye netafula lokuphendula akufani, ngoba induku kanye nokukhishwa kuzoba nobude obuhlukene, okwenza umkhiqizo ungalingani.
3. Isenzakalo selensi eshisayo: Uma i-laser idlula ngelensi yokubona (i-refraction, reflection), ilensi iyashisa futhi ibangele ukuwohloka okuncane.Lokhu kuguqulwa kuzodala ukwanda kokugxila kwe-laser kanye nokufinyezwa kobude bokugxila.Lapho umshini umile futhi nebanga lishintshwa ekugxilwe kulo, ngemva kokuvulwa kwe-laser isikhathi esithile, ukuminyana kwamandla e-laser esebenza ezintweni ezibonakalayo kuyashintsha ngenxa yesenzakalo se-lensing eshisayo, okuholela ekungalinganini okunomthelela ekutholeni amaphuzu. .
4. Uma, ngenxa yezizathu ezibonakalayo, izakhiwo zeqoqo lezinto ezingahambisani, izinguquko ezingokomzimba nezamakhemikhali eziwumphumela nazo zizohluka.Izinto ezibonakalayo zizwela kakhulu ekuphenduleni kwe-laser.Ngokuvamile, umthelela wesici uhlala njalo, kodwa izici ezingahlobene ziholela ekulimaleni komkhiqizo.Umphumela uchemile ngoba inani lamandla e-laser elingatholwa impahla ngayinye lihlukile, okuholela ekungalingani emkhiqizweni.
