Umbono omusha we-optical modulation

Umbono omusha we-optical modulation

Ukulawula ukukhanya,ukuguqulwa kwe-opticalimibono emisha.

Muva nje, ithimba labacwaningi base-United States naseCanada bashicilele ucwaningo olusha olumemezela ukuthi babonise ngempumelelo ukuthi umsebe we-laser ungaveza izithunzi njengento eqinile ngaphansi kwezimo ezithile. Lolu cwaningo luphonsela inselelo ukuqonda kwemiqondo yesithunzi yendabuko futhi luvula amathuba amasha obuchwepheshe bokulawula i-laser.

Ngokwesiko, izithunzi zivame ukudalwa izinto ezingacacile ezivimba umthombo wokukhanya, futhi ukukhanya kuvame ukudlula kwezinye imishayo ngaphandle kwezithiyo, ngaphandle kokuphazamisana. Kodwa-ke, ososayensi bathole ukuthi ngaphansi kwezimo ezithile, i-laser beam ngokwayo ingasebenza "njengento eqinile", ivimbele enye i-light yokukhanya futhi ngaleyo ndlela ikhiphe isithunzi emkhathini. Lesi simo sibonga ukwethulwa kwenqubo ye-optical engaqondile evumela ukuthi i-beam eyodwa yokukhanya ihlangane nenye ngokuncika kokuqina kwento, ngaleyo ndlela ithinte indlela yayo yokusabalalisa nokudala umphumela wethunzi. Esivivinyweni, abacwaningi basebenzise i-laser eluhlaza enamandla amakhulu ukuze badlule ku-ruby crystal ngenkathi bekhanyisa i-laser eluhlaza okwesibhakabhaka ohlangothini. Lapho i-laser eluhlaza ingena ku-ruby, endaweni ishintsha impendulo yezinto ezibonakalayo ibe ukukhanya okuluhlaza okwesibhakabhaka, okwenza i-laser eluhlaza isebenze njengento eqinile, ivimbe ukukhanya okuluhlaza okwesibhakabhaka. Lokhu kusebenzisana kubangela indawo emnyama ekukhanyeni okuluhlaza okwesibhakabhaka, indawo yomthunzi we-laser eluhlaza.

Lo mphumela "we-laser shadow" uwumphumela wokumuncwa okungahambisani ne-ruby crystal. Ngokukhethekile, i-laser eluhlaza ithuthukisa ukumuncwa kwe-optical yokukhanya okuluhlaza okwesibhakabhaka, idale indawo yokukhanya okuphansi ngaphakathi kwesifunda esikhanyisiwe, idale isithunzi esibonakalayo. Lesi sithunzi asikwazi ukubonwa ngokuqondile ngeso lenyama kuphela, kodwa futhi ukuma kwayo kanye nesimo saso singahambisana nesimo nokuma kweugongolo laser, ukuhlangabezana nazo zonke izimo zesithunzi sendabuko. Ithimba labacwaningi lenze ucwaningo olunzulu ngalesi simo futhi lalinganisa umehluko wethunzi, okukhombisa ukuthi umehluko omkhulu wethunzi ufinyelela cishe ku-22%, okufana nokungafani kwethunzi elichithwa yizihlahla elangeni. Ngokusungula imodeli yetiyetha, abacwaningi baqinisekisa ukuthi imodeli ingakwazi ukubikezela ngokunembile ukushintshwa kokuhluka kwethunzi, okubeka isisekelo sokuqhubeka nokusetshenziswa kobuchwepheshe. Ngokombono wezobuchwepheshe, lokhu kutholwa kunezinhlelo zokusebenza ezingaba khona. Ngokulawula ukushuba kokudluliswa kwesinye isigxobo se-laser siye kwenye, lobu buchwepheshe bungasetshenziswa ekushintsheni kokubona, ekulawuleni ukukhanya okunembayo namandla aphezulu.ukudluliswa kwe-laser. Lolu cwaningo lunikeza isiqondiso esisha sokuhlola ukusebenzisana phakathi kokukhanya nokukhanya, futhi kulindeleke ukuthi lukhuthaze ukuthuthukiswa okuqhubekayo kweubuchwepheshe be-optical.
