Gusobanukirwa Uruziga rw'Umurimo muri Lazeri za Semiconductor: Igisobanuro Gikomeye Kiri Inyuma y'Igipimo Gito

Mu ikoranabuhanga rya none rya optoelectronic, laser za semiconductor zigaragara cyane kubera imiterere yazo nto, imikorere yazo myiza, no kwihuta. Zigira uruhare runini mu nzego nko mu itumanaho, ubuvuzi, gutunganya inganda, no kumenya/gupima. Ariko, iyo uganira ku mikorere ya laser za semiconductor, ikintu kimwe gisa n'aho cyoroshye ariko cy'ingenzi cyane - uruziga rw'inshingano - gikunze kwirengagizwa. Iyi ngingo iragerageza gusuzuma igitekerezo, imibare, ingaruka, n'akamaro k'uruziga rw'inshingano muri sisitemu za laser za semiconductor.

1. Urugendo rw'inshingano ni iki?

Uruziga rw'umurimo ni igipimo kitagira ingano gikoreshwa mu gusobanura igihe laser iri mu mimerere ya "kuri" mu gihe kimwe nyuma y'ikimenyetso gisubiramo. Ubusanzwe kigaragazwa nk'ijanisha. Ifishi ni: Uruziga rw'umurimo = (Ubugari bw'ingufu/Igihe cyo gutera umuvuduko w'amaraso (pulse periode)×100%. Urugero, niba laser isohora umuvuduko wa microsegonda 1 buri microsegonda 10, imikorere y'umuvuduko ni: (1 μs/10 μs)×100%=10%.

2. Kuki akazi gakorwa ku nshuro ya mbere ari ingenzi?

Nubwo ari igipimo gusa, imikorere y'uruhererekane rw'ingufu igira ingaruka zitaziguye ku micungire y'ubushyuhe bwa laser, igihe ikora, imbaraga zisohoka, ndetse n'imiterere ya sisitemu muri rusange. Reka turebe akamaro kayo:

① Imicungire y'ubushyuhe n'ubuzima bwose bw'igikoresho

Mu bikorwa byo gushyushya hakoreshejwe amashanyarazi menshi, imikorere y’amashanyarazi make bivuze igihe kirekire cyo "kuruhuka" hagati y’imikorere y’amashanyarazi, ibi bifasha laser gukonja. Ibi ni ingirakamaro cyane cyane mu bikorwa bifite ingufu nyinshi, aho kugenzura imikorere y’amashanyarazi bishobora kugabanya ubushyuhe no kongera igihe cyo gukoresha igikoresho.

② Ingufu zisohoka n'ubukana bw'urumuri

Ihindagurika ry’ingufu rituma habaho umusaruro mwinshi w’amatara, mu gihe ihindagurika ry’ingufu rigabanya imbaraga zisanzwe. Guhindura ihindagurika ry’ingufu bifasha mu kunoza ingufu zisohoka hatabayeho guhindura umuvuduko w’amashanyarazi ukoreshwa mu gihe cy’ingufu.

③ Uburyo bwo gusubiza no guhindura ibimenyetso bya sisitemu

Mu itumanaho rya optique na sisitemu za LiDAR, imikorere y'ingufu igira ingaruka ku buryo butaziguye ku gihe cyo gusubiza no ku buryo bwo guhindura imikorere. Urugero, mu buryo bwo gupima imikorere ya laser, gushyiraho imikorere ikwiye y'ingufu binoza uburyo bwo kubona ibimenyetso bya echo, bikongera uburyo bwo gupima no gupima inshuro.

3. Ingero z'Ishyirwa mu Bikorwa ry'Imirimo

① LiDAR (Gupima no Gupima Lazeri)

Muri module za laser za 1535nm, imiterere y'amajwi yo hasi kandi yo hejuru ikoreshwa mu kugenzura ko amaso ashobora kumenyekana kure ndetse no mu mutekano w'amaso. Imikorere y'amajwi akenshi igenzurwa hagati ya 0.1% na 1%, ihuza imbaraga zo hejuru hamwe n'imikorere yizewe kandi ikonje.

② Imirasire y'Ubuvuzi ya Laser

Mu bikorwa nko kuvura uruhu cyangwa kubagwa hakoreshejwe laser, imikorere itandukanye ivamo ingaruka zitandukanye z'ubushyuhe n'ingaruka zo kuvura. Imikorere myinshi itera ubushyuhe burambye, mu gihe imikorere mike ifasha mu gutanga impumuro y'ubwonko ako kanya.

③ Gutunganya ibikoresho by'inganda

Mu gushyira ikimenyetso no gusudira hakoreshejwe laser, imikorere y'ingufu igira ingaruka ku buryo ingufu zishyirwa mu bikoresho. Guhindura imikorere y'ingufu ni ingenzi mu kugenzura uburebure bw'ibishushanyo n'uburyo binjira mu gusudira.

4. Ni gute wahitamo urwego rw'inshingano rukwiye?

Uruhererekane rw'imirimo myiza rushingira ku ikoreshwa ryihariye n'imiterere ya laser:

①Urugendo rw'akazi gake (<10%)

Ni byiza cyane mu gukoresha uburyo bwo gupima uburebure bw'umuvuduko muremure, nko gushyira ku murongo cyangwa gushyira ku murongo neza.

②Urugendo rw'akazi gaciriritse (10%–50%)

Bikwiriye gukoresha sisitemu za laser zikoresha pulse nyinshi.

③Urugendo rw'akazi kenshi (>50%)

Igenda ikoreshwa mu miyoboro ihoraho (CW), ikoreshwa mu bikorwa nko gupompa amatara no mu itumanaho.

Izindi ngingo zo gusuzuma zirimo ubushobozi bwo gukwirakwiza ubushyuhe, imikorere y'uruziga rw'umushoferi, ndetse n'ubushyuhe bwa laser.

5. Umwanzuro

Nubwo ari nto, uruziga rw'akazi ni ikintu cy'ingenzi mu gushushanya sisitemu za laser za semiconductor. Ntibigira ingaruka gusa ku musaruro w'imikorere ahubwo binagira ingaruka ku ituze n'ubudahemuka by'iyi sisitemu mu gihe kirekire. Mu iterambere n'ikoreshwa rya laser mu gihe kizaza, kugenzura neza no gukoresha neza uruziga rw'akazi bizaba ingenzi mu kunoza imikorere ya sisitemu no gutuma habaho udushya.

Niba ufite ibindi bibazo bijyanye n'igishushanyo cyangwa porogaramu za laser, hamagara cyangwa utange igitekerezo. Turi hano kugufasha!
