Eduze vs. I-Mid-Infrared Light for Face Analysis

Ake ucabange ngezwe lapho ukuhlonza ubuso ezimeni ezingakhanyi kahle kulula njengokungena ekamelweni elingakhanyi kahle. I-Near-infrared (NIR) kanye ne-mid-infrared (MIR) ukukhanya kuguqula ukubonwa kobuso nokuxilongwa ngezindlela ebezingacatshangwa ngaphambili. Lobu buchwepheshe obusha buguqule ezokuphepha, ukunakekelwa kwezempilo, nokunye okwengeziwe, kodwa buhluke kanjani, futhi kufanele busetshenziswe nini ngalunye?

Ukuqonda Ukukhanya Kwe-Infrared: Eduze vs. Mid-Infrared

Ukukhanya kwe-infrared (IR) kuwuchungechunge olungabonakali lwemisebe ye-electromagnetic, enamaza amaza amade kunalawo okukhanya okubonakalayo. Iphinde ihlukaniseke phakathi kwe-infrared eseduze (NIR) kanye ne-mid-infrared (MIR), ngayinye enezici ezihlukile nezindlela zokusebenza.
Ukukhanya okuseduze kwe-infrared, okumboza ububanzi obusuka ku-0.7 kuya ku-1.4 micrometer, kusebenza kahle ekuhlaziyeni izinga eliphezulu. Ingena esikhunjeni ngaphandle kokudala umonakalo, iyenze ilungele ukuqinisekiswa kwe-biometric nezinyathelo zokuphepha. Isibonelo, ezikhumulweni zezindiza, amakhamera e-NIR aqinisekisa ukuthi abahambi bayilabo abathi bayikho ngisho nasezimeni zokukhanya okuphansi. Lobu buchwepheshe buncike emaphethini emvelo okugeleza kwegazi esikhumba, okunikeza indlela eqinile nethembekile yokuhlonza.
Ukukhanya kwe-infrared okumaphakathi, okusuka kuma-micrometer angu-3 kuye kwayi-8, kunikeza imininingwane ejulile ngesakhiwo samangqamuzana esikhumba. Isebenzisana namabhondi amakhemikhali kuma-molecule esikhumba, ihlinzeka ngezinhlelo ezikhethekile ku-dermatology kanye ne-thermal imaging. Isibonelo, ku-dermatology, i-MIR ingathola izinguquko ezicashile ekushiseni kwesikhumba ezingase zibonise izinkinga zempilo eziyisisekelo njengokuvuvukala noma izifo.

Ukusetshenziswa Kokukhanya Okuseduze Kwe-Infrared Ebusweni Ukuhlaziya

Ukukhanya kwe-NIR kuye kwamukelwa kabanzi ezinhlelweni zokuqaphela ubuso ngenxa yekhono layo lokusebenza ngokuphumelelayo ezimweni zokukhanya okuphansi. Iwusizo ikakhulukazi ezinhlelweni zokuphepha lapho ukuhlonza okucacile kubalulekile. Ezikhumulweni zezindiza nasezindaweni zokuhlola zokulawula imingcele, amakhamera e-NIR aqinisekisa ukuthi abahambi bahlonzwa ngokunembile ngaphandle kwesidingo sokukhanya okwengeziwe. Ubuchwepheshe abuthembeki nje kuphela kodwa futhi buyabiza, okwenza kube ukukhetha okuthandwayo ezimbonini ezihlukahlukene.
Ekuxilongweni kwezokwelapha, ukukhanya kwe-NIR kusetshenziselwa ukuhlaziya ukugeleza kwegazi nokwakheka kwezicubu. Isibonelo, ku-dermatology, i-NIR ingasiza ekutholeni izimpawu zokuqala zezimo zesikhumba nezifo. Ucwaningo luye lwabonisa ukuthi ubuchwepheshe be-NIR bungaqapha ngempumelelo impilo yesikhumba, bunikeze ukuqonda okubalulekile okungase kugejwe izindlela zendabuko. Le ndlela engahlaseli ikwenza kube ithuluzi elibalulekile lokuqapha impilo okuqhubekayo.

Ukuhlola Ukukhanya Kwe-Mid-Infrared Ukuhlaziya Ubuso

Ngenkathi i-NIR isetshenziswa kabanzi ezinhlelweni ezisebenzayo, i-MIR inezinzuzo zayo ezihlukile. Ngokusebenzisana nezibopho zamakhemikhali kuma-molecule esikhumba, i-MIR inikeza ulwazi oluningiliziwe mayelana nokwakheka kwesikhumba kanye nezakhiwo ezishisayo. Lobu buchwepheshe buwusizo ikakhulukazi emikhakheni ekhethekile efana ne-dermatology ne-thermal imaging. Isibonelo, i-MIR ingasiza ekutholeni okungavamile ekushiseni kwesikhumba, okungabonisa izinkinga zempilo eziwumsuka njengokuvuvukala noma izifo.
Ubuchwepheshe be-MIR, nokho, bubhekene nezinselelo ezimbalwa. Kuyinkimbinkimbi futhi kubiza kakhulu ukukusebenzisa kune-NIR, ekhawulela ukusetshenziswa kwayo okusabalele. Noma kunjalo, ikhono layo lokuhlinzeka ngemininingwane ejulile liyenza ibe wusizo ezinhlelweni ezithile zezokwelapha nezocwaningo. Isibonelo, ku-dermatology, i-MIR ingaqapha izimo zesikhumba ngokuhamba kwesikhathi, inikeze ukuqonda okuphelele okwengeziwe kwempilo yesikhumba. Lokhu kuyenza ibe ithuluzi elincanyelwayo lezinhlelo zokusebenza ezinemininingwane nezikhethekile lapho ukuhlaziywa kwezinga eliphezulu kunganele.

Ukuhlaziywa Okuqhathanisayo: Eduze vs. Ukukhanya Kwe-Mid-Infrared

Kokubili i-NIR ne-MIR zinikeza izinzuzo ezihlukile ekuhlaziyeni ubuso. I-NIR iphumelela kakhulu ekuhlaziyeni izinga eliphezulu futhi iyonga, okwenza ilungele izinhlelo zokusebenza ezisabalele njengamasistimu okuvikela kanye nokuxilongwa kwezokwelapha okuyisisekelo. I-MIR, ngakolunye uhlangothi, inikeza ukuqonda okujulile ngesakhiwo samangqamuzana esikhumba kodwa ngezindleko eziphakeme kanye nesidingo sobuchwepheshe. Ukukhetha phakathi kwabo kuncike ezidingweni ezithile zomsebenzi, njengokujula kokuhlaziya kanye nemikhawulo yesabelomali.

Izinselele kanye namathemba esikhathi esizayo ekuhlaziyweni kobuso be-infrared

Sengiphetha, kokubili ukukhanya okuseduze naphakathi kwe-infrared kunikeza iminikelo ebalulekile kubuchwepheshe bobuso, ngakunye nesethi yayo yamakhono ahlukile. Ngenkathi i-NIR iqhubeka nokubusa izicelo ezingokoqobo ngenxa yokufinyeleleka kwayo nokuguquguquka, i-MIR inamandla okuhlaziya okukhethekile, okujulile. Njengoba ucwaningo luqhubeka, i-spectrum ye-infrared ngokungangabazeki izodlala indima ebalulekile esikhathini esizayo sokuhlaziya ubuso, iqhubekisele phambili izinto ezintsha ezithuthukisa ukuqonda kwethu nokusebenzisa ubuchwepheshe bobuso. Ucwaningo oluqhubekayo nokuthuthukiswa kuzoba semqoka ekusebenziseni ngokugcwele amandla okukhanya kwe-infrared ukuze kuhlaziywe ubuso, kuvule indlela yentuthuko eyisisekelo.
