Reba guhitamouburyo bumwe bwa fibre laser
Mubikorwa bifatika, guhitamo uburyo bumwe bukwiyelaserbisaba gupima buri gihe ibipimo bitandukanye kugirango tumenye neza ko imikorere yayo ihuye nibisabwa byihariye bisabwa, ibidukikije bikora n'imbogamizi. Iki gice kizatanga uburyo bufatika bwo guhitamo bushingiye kubisabwa.
Ingamba zo gutoranya zishingiye ku bikorwa
Imikorere ibisabwa kurilaseriBitandukanye cyane muburyo butandukanye bwo gusaba. Intambwe yambere muguhitamo ni ugusobanura ibyifuzo byibanze bya porogaramu.
Gutunganya ibikoresho neza no gukora micro-nano: Porogaramu nkizo zirimo gukata neza, gucukura, semiconductor wafer, gushushanya urwego rwa micron no gucapa 3D, nibindi. Lazeri ifite M² ibintu hafi ya 1 (nka <1.1) igomba guhitamo. Imbaraga zisohoka zigomba kugenwa hashingiwe ku bunini bwibintu no kwihuta. Mubisanzwe, imbaraga kuva kuri mirongo kugeza kuri magana watts zirashobora kuzuza ibisabwa na mikoro myinshi. Kubijyanye nuburebure bwumurongo, 1064nm niyo ihitamo guhitamo ibikoresho byinshi byicyuma bitewe nigipimo cyinshi cyo kwinjiza hamwe nigiciro gito kuri watt yingufu za laser.
Ubushakashatsi bwa siyansi hamwe no gupima ibintu byo mu rwego rwo hejuru: Ibihe byo gusaba birimo optiki ya optique, fiziki ya atome ikonje, ibisubizo bihanitse bya spekitroscopi na interferometrie. Iyi mirima mubisanzwe ifite gukurikirana cyane monochromaticité, ituze ryinshyi hamwe n urusaku rwimikorere ya laseri. Icyitegererezo gifite umurongo muto (ndetse numurongo umwe) hamwe n urusaku ruke cyane bigomba guhabwa umwanya wambere. Uburebure bwumurongo bugomba gutoranywa hashingiwe kumurongo wa resonance ya atom cyangwa molekile yihariye (urugero, 780nm ikoreshwa mugukonjesha atome ya rubidium). Kubungabunga kubogama mubisanzwe birakenewe mubigeragezo byo kwivanga. Imbaraga zisabwa muri rusange ntabwo ziri hejuru, kandi miliwatt ijana kugeza kuri watt nyinshi zirahagije.
Ubuvuzi na biotechnologiya: Mubisabwa harimo kubaga amaso, kuvura uruhu hamwe na microscopi ya microscopi ya fluorescence. Umutekano w'amaso nicyo kintu cyambere gitekerezwaho, bityo laseri ifite uburebure bwa 1550nm cyangwa 2μm, ziri mumurongo wumutekano wamaso, akenshi zirahitamo. Kubisabwa byo gusuzuma, hagomba kwitonderwa imbaraga zihamye; Kubikorwa byo kuvura, imbaraga zikwiye zigomba gutoranywa hashingiwe ku burebure bwo kuvura n'ibisabwa ingufu. Ihinduka ryimikorere ya optique ninyungu nini mubikorwa nkibi.
Itumanaho no Kumva: Fibre optique sensing, liDAR hamwe nu mwanya wa optique itumanaho nibisanzwe. Ibi bintu bisabalaserkugira ubwizerwe buhanitse, guhuza ibidukikije no gutuza igihe kirekire. Itsinda rya 1550nm ryahindutse ihitamo bitewe no gutakaza kwayo kwinshi muri fibre optique. Kuri sisitemu yo gutahura (nka lidar coherent), lazeri ifite umurongo wa polarize ifite umurongo muto cyane urasabwa nka oscillator yaho.
2. Gutondekanya ibyingenzi byingenzi
Guhura nibintu byinshi, ibyemezo birashobora gufatwa hashingiwe kubyingenzi bikurikira:
Ibipimo bifatika: Icya mbere, menya uburebure bwumuraba nubuziranenge bwibiti. Uburebure bwumurongo bugenwa nibisabwa byingenzi mubisabwa (ibiranga kwinjiza ibintu, ibipimo byumutekano, imirongo ya atome resonance), kandi mubisanzwe nta mwanya wo kumvikana. Ubwiza bwibiti bugena muburyo bwibanze bushoboka bwa porogaramu. Kurugero, gutunganya neza ntibishobora kwakira laseri hamwe na M² birenze urugero.
Ibipimo by'imikorere: Icya kabiri, witondere ibisohoka imbaraga n'umurongo w'ubugari / polarisiyasi. Imbaraga zigomba kuba zujuje ingufu zingana cyangwa ibisabwa neza mubisabwa. Ibiranga umurongo hamwe na polarisiyonike bigenwa hashingiwe ku nzira yihariye ya tekinike ya porogaramu (nko kuba intambamyi cyangwa inshuro ebyiri zirimo). Ibipimo bifatika: Hanyuma, tekereza ku gutekana (nkigihe kirekire gisohoka imbaraga zihamye), kwizerwa (igihe cyo gukora nta makosa), gukoresha ingufu zingana, guhuza ibiciro hamwe nigiciro. Ibipimo bigira ingaruka kubibazo byo kwishyira hamwe nigiciro rusange cyo gutunga laser mubikorwa nyabyo bikora.

3. Guhitamo no guca imanza hagati yuburyo bumwe nuburyo bwinshi
Nubwo iyi ngingo yibanze ku buryo bumwelaseri, ni ngombwa kumva neza ko ari ngombwa guhitamo uburyo bumwe muburyo bwo guhitamo. Iyo ibisabwa byibanze bya porogaramu aribwo buryo bwo gutunganya neza, agace gato gaterwa nubushyuhe, ubushobozi bwibanze bwo kwibandaho cyangwa intera ndende yohereza, lazeri imwe ya fibre yonyine niyo ihitamo neza. Ibinyuranye, niba porogaramu ikubiyemo cyane cyane gusudira isahani yuzuye, kuvura ahantu hanini cyane cyangwa kuvura intera ndende-ndende, kandi ibisabwa byuzuye ntabwo ari hejuru, noneho lazeri ya fibre fibre irashobora guhinduka muburyo bwubukungu kandi bufatika bitewe nimbaraga zabo zose hamwe nigiciro gito.
