Ingufu za Pulse ya Er: Ikirahure cya Laser

Mubice bya lazeri iringaniye, igenamigambi, hamwe na LiDAR, Er: Ikwirakwiza ry'ikirahure rya lazeri ryakoreshejwe cyane hagati ya infrarafaride ikomeye ya lazeri kubera umutekano mwiza w'amaso hamwe no gushushanya. Mubikorwa byabo, imbaraga za pulse zigira uruhare runini muguhitamo ubushobozi bwo gutahura, gukwirakwiza intera, hamwe na sisitemu yitabira muri rusange. Iyi ngingo itanga isesengura ryimbitse ryingufu za pulse ya Er: Ikirahure cya laser.

1. Ingufu za Pulse ni iki?

Ingufu za pulse bivuga ingano yingufu zitangwa na laser muri buri pulse, mubisanzwe bipimirwa muri milijoules (mJ). Nibicuruzwa byimbaraga nimbaraga zigihe: E = P._impingaΤ. Aho: E ni imbaraga za pulse, P._impinga ni imbaraga zo hejuru,τ ni ubugari bwa pulse.

Kubisanzwe Er: Lazeri yikirahure ikora kuri 1535 nm-uburebure bwumurongo mugice cya 1 kirinda amaso-imbaraga nyinshi za pulse zirashobora kugerwaho mugihe kubungabunga umutekano, bigatuma bikenerwa cyane cyane kubikururwa no hanze.

2. Impanuka zingufu za Er: Ikirahure

Ukurikije igishushanyo, uburyo bwa pompe, hamwe nibisabwa gukoreshwa, ubucuruzi Er: Ikirahure cya lazeri itanga ingufu za pulse imwe kuva kuri microjoules mirongo (μJ) kugeza kuri milijoules nyinshi (mJ).

Mubisanzwe, Er: Ikirahure cya lazeri ikoreshwa muri miniature iringaniye ifite ingufu zingana na 0.1 kugeza 1 mJ. Kubantu barebare barebare, mJ 5 kugeza kuri 20 mubisanzwe birasabwa, mugihe sisitemu yo murwego rwa gisirikari cyangwa inganda zishobora kurenga 30 mJ, akenshi ikoresha ibyuma bibiri cyangwa ibyiciro byinshi byongera imbaraga kugirango bigere kumusaruro mwinshi.

Ingufu zisumba izindi muri rusange zitanga imikorere myiza yo gutahura, cyane cyane mubihe bitoroshye nkibimenyetso byo kugaruka bidakomeye cyangwa kwangiza ibidukikije kurwego rurerure.

3. Ibintu bigira ingaruka ku mbaraga za pulse

①Amashanyarazi Inkomoko

Er: Lazeri yikirahuri isanzwe ivomwa na laser diode (LDs) cyangwa flashlamps. LD zitanga imikorere ihanitse kandi yoroheje ariko isaba kugenzura neza ubushyuhe no gutwara ibinyabiziga.

②Kwibanda kwa Doping hamwe n'uburebure bwa Rod

Ibikoresho bitandukanye byakira nka Er: YSGG cyangwa Er: Yb: Ikirahure kiratandukanye murwego rwa doping kandi bikagira uburebure, bigira ingaruka mubushobozi bwo kubika ingufu.

③Ikibazo-Guhindura Ikoranabuhanga

Guhindura Q-guhinduranya (urugero, hamwe na Cr: YAG kristu) byoroshya imiterere ariko bitanga kugenzura neza. Guhindura Q-guhinduranya (urugero, hamwe na selile ya Pockels) itanga umutekano muke no kugenzura ingufu.

④Gucunga Ubushyuhe

Ku mbaraga nyinshi, imbaraga zogukwirakwiza ubushyuhe bwa laser hamwe nuburyo bwibikoresho ni ngombwa kugirango umusaruro uhamye kandi urambe.

4. Guhuza Ingufu Zingufu Kuri Porogaramu

Guhitamo iburyo Er: Ikirahure laser transmitter biterwa cyane na porogaramu igenewe. Hano haribintu bimwe bisanzwe bikoreshwa hamwe nibyifuzo byingufu za pulse:

①Ikiganza cya Laser Rangefinders

Ibiranga: byegeranye, imbaraga nke, ibipimo byinshi-bigufi bipima

Basabwe Ingufu Zingufu: 0.5-1 mJ

②Indege ya UAV / Kwirinda inzitizi

Ibiranga: hagati-ndende-ndende, igisubizo cyihuse, cyoroshye

Basabwe Ingufu Zingufu: 1-5 mJ

③Abashinzwe Intego za Gisirikare

Ibiranga: kwinjira cyane, kurwanya-kwivanga, kuyobora intera ndende

Basabwe Ingufu Zingufu: 10-30 mJ

④Sisitemu ya LiDAR

Ibiranga: igipimo kinini cyo gusubiramo, gusikana cyangwa kwerekana igicu

Basabwe Ingufu Zingufu: 0.1-10 mJ

5. Ibihe bizaza: Ingufu nyinshi & Gupakira

Hamwe niterambere rigenda rikorwa muburyo bwa tekinoroji ya doping, ibikoresho bya pompe, nibikoresho byubushyuhe, Er: Imashini itanga ibirahure bigenda byiyongera bigahuzwa ningufu nyinshi, umuvuduko mwinshi wo gusubiramo, na miniaturizasi. Kurugero, sisitemu ihuza ibyiciro byinshi byongerewe imbaraga hamwe na Q-ihinduranya igishushanyo gishobora gutanga mJ zirenga 30 kuri pulse mugihe gikomeza ibintu bifatika.-nibyiza kubipimo birebire byo gupima hamwe no kwizerwa cyane kurinda porogaramu.

6. Umwanzuro

Ingufu za pulse nigikorwa cyingenzi cyerekana gusuzuma no guhitamo Er: Ikirahure cya laser yoherejwe hashingiwe kubisabwa. Mugihe tekinoroji ya laser ikomeje kugenda itera imbere, abayikoresha barashobora kugera kumusaruro mwinshi kandi murwego runini mubikoresho bito, bikoresha ingufu nyinshi. Kuri sisitemu isaba imikorere ndende, umutekano wamaso, hamwe nubwizerwe bwibikorwa, gusobanukirwa no guhitamo ingufu zingirakamaro zingirakamaro ningirakamaro mugutezimbere imikorere nagaciro.

Niba ari wowe're ushakisha imikorere-ikomeye Er: Ikirahure cya laser yoherejwe, wumve neza. Dutanga moderi zitandukanye hamwe ningufu za pulse zisobanutse kuva kuri 0.1 mJ kugeza hejuru ya 30 mJ, bikwiranye nurwego runini rwa porogaramu muri laser range, LiDAR, no kugena intego.
