Isixazululo sesistimu yokucubungula i-laser
Ukunqunywa kweukucutshungulwa kwe-laserIsixazululo sesistimu ye-optical sincike esimweni esithile sohlelo lokusebenza. Izimo ezahlukene ziholela ezixazululweni ezahlukene zesistimu ye-optical. Ukuhlaziywa okuqondile kuyadingeka kwezinhlelo ezithile zokusebenza. Uhlelo lwe-optical luboniswe kuMfanekiso 1:

Indlela yokucabanga yile: imigomo yenqubo eqondile –i-laserizici – ukwakheka kohlelo lwe-optical – ukufezwa komgomo wokugcina. Okulandelayo yizinkambu eziningana ezahlukene zohlelo lokusebenza:
1. Insimu yokucubungula okuncane ngokunemba (ukumaka, ukuqopha, ukubhoboza, ukusika okunembile, njll.) Izinqubo ezivamile ezivamile ensimini yokucubungula okuncane ngokunemba ukucutshungulwa kwe-micro-metric ezintweni ezifana nezinsimbi, izinto zobumba, nengilazi, njengokumaka ilogo yamafoni aphathwayo, ama-stents ezokwelapha, imigodi emincane yama-nozzles okujova uphethiloli wegesi, njll. Imfuneko eyinhloko enqubweni yokucubungula yile: okokuqala, kumele ihlangabezane nezindawo zokukhanya ezincane kakhulu ezigxile, ukuminyana kwamandla aphezulu kakhulu, kanye nendawo encane kakhulu yethonya lokushisa, njll. Ngezicelo nezidingo ezingenhla, ukukhethwa kanye nokuklama kweimithombo yokukhanya kwe-lasernezinye izingxenye ziyasetshenziswa.
a. Ukukhethwa kwe-Laser: I-laser eqinile ye-ultraviolet/green (nanosecond) noma i-laser ye-ultrafast (picosecond, femtosecond) ekhethwayo ibangelwa kakhulu yizizathu ezimbili. Esinye ukuthi ubude be-wavelength buhambisana nendawo yokukhanya egxilile, futhi ngokuvamile kukhethwa ubude be-wavelength obufushane. Esesibili ukuthi ama-pulse e-picosecond/femtosecond anesici "sokucubungula okubandayo", futhi amandla aqedwa ukucubungula ngaphambi kokusabalalisa kokushisa, okufeza ukucubungula okubandayo. Ngokuvamile, kukhethwa umthombo wokukhanya we-laser onokukhishwa kokukhanya kwendawo, onesici sekhwalithi ye-beam M2 ngokuvamile esingaphansi kuka-1.1, esinekhwalithi ye-beam ephezulu.
b. Uhlelo lokwandisa imisebe kanye nohlelo lwe-collimating ngokuvamile zisebenzisa amalensi okwandisa imisebe eguquguqukayo (2X - 5X), ezama ukwandisa ububanzi bomsebe ngangokunokwenzeka. Ububanzi bomsebe buhambisana ngokuphambene nendawo yokukhanya egxilile, futhi ngokuvamile kusetshenziswa ukwakheka kokukhulisa imisebe yaseGalilean.
c. Uhlelo lokugxila luvame ukusebenzisa amalensi e-F-Theta asebenza kahle kakhulu (ukuskena) noma amalensi okugxila e-telecentric. Ubude be-focal buhambisana nendawo yokukhanya egxilile, futhi ngokuvamile kusetshenziswa amalensi amafushane e-focal field (njenge-f = 50mm, 100mm). Njengoba kuboniswe kuMfanekiso 1: Ngokuvamile, ilensi yensimu isebenzisa iqembu lelensi elinama-element amaningi (inani lamalensi ≥ 3), elingafinyelela umbono omkhulu, ukuvuleka okukhulu, kanye nezinkomba eziphansi zokuphambuka. Amalensi optical lapha wonke adinga ukucabangela umkhawulo womonakalo we-laser.
d. Uhlelo lokubona lwe-Coaxial: Kuhlelo lokubona, uhlelo lokubona lwe-coaxial (CMOS) luvame ukuhlanganiswa ukuze kubekwe indawo enembile kanye nokuqapha ngesikhathi sangempela inqubo yokucubungula.
2. Ukucubungula izinto ezinkulu Izimo ezijwayelekile zokusetshenziswa kokucubungula izinto ezinkulu zihlanganisa ukusika izinto zeshidi lezimoto, ukushisela amapuleti ensimbi omzimba womkhumbi, kanye nokushisela amagobolondo ezindlu zebhethri. Lezi zinqubo zidinga amandla aphezulu, ikhono eliphezulu lokungena, ukusebenza kahle okuphezulu, kanye nokuqina kokucubungula.
3. Ukukhiqizwa kwezengezo ze-laser (ukuphrinta kwe-3D) kanye nokukhiqizwa kwezengezo ze-laser (ukuphrinta kwe-3D) kanye nezicelo zezengezo ze-laser ngokuvamile kuhilela izinqubo ezilandelayo ezijwayelekile: ukuphrinta kwensimbi okuyinkimbinkimbi yezindiza, ukulungiswa kwe-blade yenjini, njll.
Ukukhethwa kwezingxenye eziyinhloko kungokulandelayo:
a. Ukukhethwa kwe-laser: Ngokuvamile,ama-laser e-fiber anamandla amakhuluzikhethwa, ngamandla avame ukwedlula ama-500W.
b. Ukubumba imisebe: Lolu hlelo lokubona ludinga ukukhipha ukukhanya okuyisicaba, ngakho-ke ukubumba imisebe ubuchwepheshe obuyinhloko, futhi kungafezwa kusetshenziswa izakhi zokubona ezihlukanisayo.
c. Uhlelo lokugxila: Izibuko kanye nokugxila okunamandla yizidingo eziyisisekelo ensimini yokuphrinta ye-3D. Ngesikhathi esifanayo, ilensi yokuskena idinga ukusebenzisa umklamo we-telecentric ohlangothini lwezinto ukuqinisekisa ukuhambisana kokucubungula komphetho kanye nendawo ephakathi.
