Tekonolosi leitio uaealesi: auiliiliga o mataupu faavae ma le faʻaaogaina o le tele o fanua

O le RF (Radio Frequency) e faasino i galu eletise e iai ni frequencies i le va o le 3kHz ma le 300GHz, lea e taua tele i fesootaiga, radar, togafitiga faafoma'i, pulega tau alamanuia ma isi matā'upu.

Mataupu faavae autū o le leitio

O fa'ailoilo RF e fa'atupuina e oscillators, ma o galu eletise maualuga e fa'asalalauina ma fa'asalalauina e ala i antenna. O ituaiga antenna masani e aofia ai antenna dipole, antenna horn ma antenna patch, ia e talafeagai mo tulaga fa'aoga eseese. O le itu e taliaina e toe fa'afo'isia le fa'ailoilo RF i fa'amatalaga e mafai ona fa'aaogaina e ala i se demodulator e fa'ataunu'u ai le fa'asalalauga o fa'amatalaga.

Fa'avasegaga ma metotia fa'afetaui o le leitio

E tusa ai ma le televave, e mafai ona vaevaeina le televave o leitio i ni televave maualalo (e pei o fesootaiga faasalalau), televave feololo (e pei o fesootaiga feaveaʻi), ma televave maualuga (e pei o le radar ma togafitiga faafomaʻi). O auala faʻatonutonu e aofia ai le AM ​​(mo le faʻasalalauga maualalo), FM (mo le faʻasalalauga feololo) ma le PM (mo le faʻasalalauga maualuga o faʻamatalaga).

RFID: o le tekinolosi autū o le fa'ailoaina atamai

E faʻaaogaina e le RFID (faʻailoaina o alaleo) galu eletise ma microchips e faʻatino ai le faʻailoaina otometi, ma e faʻaaogaina lautele i le faʻamaoniaina o faʻasinomaga, pulega o felauaiga, faʻatoʻaga ma fafaga manu, totogi o felauaiga ma isi matāʻupu. E ui o loʻo feagai le tekinolosi RFID ma luʻitau e pei o le tau ma le faʻatulagaina, o lona faigofie ma le lelei ua faʻalauteleina ai le atinaʻeina o le pulega atamai.

Fa'aoga lautele o tekinolosi RF

E susulu le tekinolosi RF i vaega o fesoʻotaʻiga uaealesi, fesoʻotaʻiga satelite, iloa o radar, suʻesuʻega faafomaʻi ma le puleaina o pisinisi. Mai fesoʻotaʻiga WLAN i electrocardiographs, mai suʻesuʻega o le malae taua i fale gaosimea atamai, o loʻo faʻalauiloa e le tekinolosi RF le alualu i luma o tekinolosi ma suia ai o tatou olaga.

E ui o loo feagai pea tekinolosi RF ma luitau, faatasi ai ma le atinaeina o le faasaienisi ma tekinolosi, o le a faaauau pea ona sosolo atu i mea fou ma aumaia ai nisi avanoa mo le lumanai!
