Kuyini iTerahertz? Ukuqonda Imisebenzi yeTerahertz
Imisebe ye-Terahertz (THz), evame ukubizwa ngokuthi "igebe le-terahertz," ithatha indawo eyingqayizivele ku-spectrum ye-electromagnetic, elele phakathi kwama-microwave kanye nemisebe ye-infrared. Leli bhendi livame ukuba phakathi kwama-terahertz angu-0.1 kuya kwangu-10 kanye ubude be-wavelength kusukela kumamilimitha amathathu kuya kuma-micrometer angu-30. Kodwa iyini ngempela i-terahertz? Futhi yiziphi izindima ezenzayo emikhakheni eyahlukahlukene?
Imisebe yeTerahertz ayiyona nje into entsha yesayensi; inezinhlelo zokusebenza ezingokoqobo emikhakheni eminingi. Omunye wemisebenzi yayo ebaluleke kakhulu ukuthwebula izithombe kanye ne-spectroscopy. Ukuthwebula izithombe kweTerahertz kungangena ezintweni ezahlukahlukene, okwenza kube usizo kakhulu ezindaweni ezifana nokuhlolwa kokuphepha, ukuhlolwa okungabhubhisi, kanye nokuthwebula izithombe kwezokwelapha. Isibonelo, ingathola izikhali ezifihliwe noma iziqhumane ngaphandle kwemiphumela elimazayo ye-X-ray.
Emkhakheni wezokuxhumana, ubuchwepheshe be-terahertz buyahlolwa ukuze kudluliselwe idatha ngesivinini esikhulu. Njengoba isidingo sesivinini se-inthanethi esisheshayo siqhubeka nokukhula, abacwaningi baphenya amandla amagagasi e-terahertz okudlulisa idatha ngamanani angakaze abonwe ngaphambili. Lokhu kuthembisa ukuguqula ukuxhumana okungenantambo, kuvumela isivinini sokulanda esisheshayo kanye nokuxhumana okuthuthukisiwe.
Ngaphezu kwalokho, ubuchwepheshe be-terahertz budlala indima ebalulekile ekuchazeni izinto. Ngokuhlaziya impendulo ye-terahertz yezinto, ososayensi bangathola ukuqonda okujulile ngezakhiwo zabo, njengokuqhuba kanye nokwakheka kwama-molecule. Lokhu kubaluleke kakhulu embonini yezemithi, njengoba i-terahertz spectroscopy isiza ekulawuleni ikhwalithi yemithi.
Ekuphetheni, imisebe ye-terahertz iyinkambu yocwaningo ethakazelisayo enamathemba amaningi okusetshenziswa. Kusukela ekuthuthukiseni izinyathelo zokuphepha kuya ekushayeleni ukuxhumana okusheshayo nokuthuthukisa ukuhlaziywa kwezinto, ukusetshenziswa okungenzeka kobuchwepheshe be-terahertz kukhulu kakhulu. Njengoba ucwaningo luqhubeka, singalindela ukubona ukusetshenziswa okusha kakhulu kwemisebe ye-terahertz esikhathini esizayo esiseduze.
