Izibuko Zezibuko- Ezisebenza Ngokusebenzisa Imithetho Yokuzindla
Incazelo Yomkhiqizo
Isibuko siyingxenye ye-optical esebenza ngokusebenzisa imithetho yokucabangela. Izibuko zingahlukaniswa zibe izibuko zendiza, izibuko eziyindilinga kanye nezibuko ze-aspheric ngokuvumelana nokubunjwa kwazo; ngokwezinga lokubonisa, zingahlukaniswa zibe izibuko ezibukwayo eziphelele kanye nezibuko ezibonakala kancane (ezaziwa nangokuthi ama-beam splitters).
Esikhathini esidlule, lapho kukhiqizwa izibonisi, ingilazi yayivame ukumbozwa ngesiliva. Inqubo yayo evamile yokukhiqiza ithi: ngemva kokuhwamuka kwe-vacuum ye-aluminium endaweni ephansi ephucuzeke kakhulu, ibe isigqitshwa nge-silicon monoxide noma i-magnesium fluoride. Kuzicelo ezikhethekile, ukulahlekelwa ngenxa yezinsimbi kungashintshwa ngamafilimu e-dielectric amaningi.
Ngenxa yokuthi umthetho wokukhanya awuhlangene nemvamisa yokukhanya, lolu hlobo lwengxenye lunebhande elibanzi lokusebenzisa imvamisa, elingafinyelela izifunda ze-ultraviolet ne-infrared zokukhanya okubonakalayo, ngakho ububanzi bokusebenza kwalo buba banzi futhi buba banzi. Ngemuva kwengilazi yokubona, ifilimu yesiliva yensimbi (noma i-aluminium) imbozwe nge-vacuum coating ukuze ibonise ukukhanya kwesigameko.
Ukusetshenziswa kwe-reflector ene-reflection ephezulu kungaphinda kabili amandla okukhipha i-laser; futhi kuboniswa indawo yokuqala ecwebezelayo, futhi isithombe esiveziwe asihlanekezelwa futhi asinaso isipoki, okuwumphumela wokuboniswa kwendawo yangaphambili. Uma i-reflector evamile isetshenziswa njengendawo yesibili ekhanyayo, hhayi kuphela ukubukeka okuphansi, akukho ukukhetha kubude be-wavelength, kodwa futhi kulula ukukhiqiza izithombe eziphindwe kabili. Futhi ukusetshenziswa kwesibuko sefilimu esiboshwe, isithombe esitholiwe asikona nje ukukhanya okuphezulu, kodwa futhi sinembile futhi ngaphandle kokuphambuka, ikhwalithi yesithombe icacile, futhi umbala ungokoqobo. Izibuko zangaphezulu zangaphambili zisetshenziswa kakhulu ekufanekisweni kwe-optical high-fidelity scanning.
