Umqondo omusha wokuguqulwa kwe-optical

Ukulawula ukukhanya,ukuguqulwa kokukhanyaimibono emisha.

Muva nje, ithimba labacwaningi abavela e-United States naseCanada lishicilele ucwaningo olusha olumemezela ukuthi babonise ngempumelelo ukuthi umsebe we-laser ungakhiqiza izithunzi ezifana nento eqinile ngaphansi kwezimo ezithile. Lolu cwaningo luphonsela inselelo ukuqonda imiqondo yesithunzi yendabuko futhi luvula amathuba amasha obuchwepheshe bokulawula i-laser.

Ngokwesiko, izithunzi zivame ukudalwa yizinto ezingacacile ezivimba umthombo wokukhanya, futhi ukukhanya kungadlula kwezinye izithunzi ngaphandle kwezithiyo, ngaphandle kokuphazamisana. Kodwa-ke, ososayensi bathole ukuthi ngaphansi kwezimo ezithile, umsebe we-laser ngokwawo ungasebenza “njengento eqinile”, uvimbele omunye umsebe wokukhanya ngaleyo ndlela uphonsa isithunzi esikhaleni. Lesi simo sibangelwa ukwethulwa kwenqubo yokukhanya engeyona eqondile evumela umsebe owodwa wokukhanya ukuthi usebenzisane nomunye ngokuncika kokuqina kwezinto, ngaleyo ndlela kuthinte indlela yokusabalala kwazo futhi kudale umphumela wesithunzi. Ekuhlolweni, abacwaningi basebenzise umsebe we-laser oluhlaza onamandla amakhulu ukuze udlule kukristalu we-ruby ngenkathi ukhanyisa umsebe we-laser oluhlaza ohlangothini. Lapho i-laser eluhlaza ingena ku-ruby, ishintsha impendulo yezinto ezibonakalayo ekukhanyeni okuluhlaza okwesibhakabhaka, okwenza umsebe we-laser oluhlaza usebenze njengento eqinile, uvimbele ukukhanya okuluhlaza okwesibhakabhaka. Lokhu kusebenzisana kubangela indawo emnyama ekukhanyeni okuluhlaza okwesibhakabhaka, indawo yesithunzi yomsebe we-laser oluhlaza.

Lo mphumela "wesithunzi se-laser" uwumphumela wokumuncwa okungeyona imigqa ngaphakathi kwekristalu yeruby. Ngokukhethekile, i-laser eluhlaza ithuthukisa ukumuncwa kokukhanya okuluhlaza okwesibhakabhaka, idala indawo yokukhanya okuphansi ngaphakathi kwendawo ekhanyisiwe, idala isithunzi esibonakalayo. Lesi sithunzi asikwazi ukubonwa ngqo ngamehlo enyama kuphela, kodwa futhi nesimo saso kungahambisana nendawo nesimo se-umsebe we-laser, ukuhlangabezana nazo zonke izimo zesithunzi sendabuko. Ithimba locwaningo lenze ucwaningo olujulile lwalesi simo futhi lalinganisa umehluko wezithunzi, okwabonisa ukuthi umehluko omkhulu wezithunzi ufinyelele cishe ku-22%, okufana nomehluko wezithunzi eziphonswa yizihlahla elangeni. Ngokusungula imodeli yethiyori, abacwaningi baqinisekisile ukuthi imodeli ingabikezela ngokunembile ushintsho lomehluko wezithunzi, okubeka isisekelo sokusetshenziswa okwengeziwe kobuchwepheshe. Ngokombono wobuchwepheshe, lokhu kutholwa kunezinhlelo zokusebenza ezingaba khona. Ngokulawula amandla okudlulisela kokukhanya kwe-laser eyodwa kuya kwenye, lobu buchwepheshe bungasetshenziswa ekushintsheni kwe-optical, ukulawula ukukhanya okunembile kanye namandla aphezulu.ukudluliswa kwe-laserLolu cwaningo luhlinzeka ngesiqondiso esisha sokuhlola ukusebenzisana phakathi kokukhanya nokukhanya, futhi kulindeleke ukuthi lukhuthaze intuthuko eyengeziweubuchwepheshe bokukhanya.
