Abantu abaninzi abakwazi ukwahlula phakathi kwerula yokugawula kunye nerula yamagnethi kumatshini wokulinganisa umbono.Namhlanje siza kuthetha ngomahluko phakathi kwabo.
I-grating scale yinzwa eyenziwe ngumgaqo wokuphazamiseka kokukhanya kunye ne-diffraction.Xa i-gratings ezimbini ezine-pitch efanayo zihlanganiswe kunye, kwaye imigca yenza i-engile encinci ngexesha elifanayo, ngoko ke phantsi kokukhanya kokukhanya okuhambelanayo, ukukhanya okwabiwe ngokulinganayo kunye nemigca emnyama inokubonwa kwicala elithe nkqo lemigca.Ibizwa ngokuba yiMoiré fringes, ngoko ke iMoiré fringes ziziphumo ezidityanisiweyo zokuphazamiseka kunye nokuphazamiseka kokukhanya.Xa igrayiti ishukunyiswa yinowuthi encinane, imiqukumbelo yemoiré nayo ishukunyiswa yipitch enye.Ngale ndlela, sinokulinganisa ububanzi beefringe ze-moiré lula kakhulu kunobubanzi bemigca ye-grating.Ukongezelela, ekubeni i-fringe nganye ye-moire iqulunqwe ngokuhlukana kwemigca emininzi yokugaya, xa enye yemigca inempazamo (isithuba esingalinganiyo okanye i-slant), lo mgca wempazamo kunye nomnye umgca wokugaya. .Nangona kunjalo, i-moiré fringe yenziwe ngeendlela ezininzi zokunqumla imigca.Ngoko ke, ukutshintshwa kwesikhundla somgca we-intersection kunempembelelo encinci kwi-fringe ye-moiré, ngoko ke i-fringe ye-moire ingasetyenziselwa ukwandisa kunye nomphumo ophakathi.
Umlinganiselo wamagnetic yinzwa eyenziwe ngokusebenzisa umgaqo wezibonda zamagnetic.Isiseko sayo somlawuli sisitya sentsimbi esifana nemagnethi.Izibonda zayo ze-S kunye no-N zifakwe ngokulinganayo kwintsimbi yentsimbi, kwaye intloko yokufunda ifunda utshintsho lweepali ze-S kunye no-N ukubala.
Umlinganiselo wokugaya uchaphazeleka kakhulu bubushushu, kwaye indawo yokusetyenziswa ngokubanzi ingaphantsi kwama-40 degrees Celsius.
Izikali ezivulekileyo zemagnethi zichatshazelwa lula ziindawo zemagnethi, kodwa izikali ezivaliweyo azinayo le ngxaki, kodwa ixabiso liphezulu.
