Gusobanukirwa Cycle Cycle muri Semiconductor Lasers: Ibisobanuro binini Inyuma ya Parameter Nto

Mubuhanga bugezweho bwa optoelectronic, lazeri ya semiconductor igaragara hamwe nuburyo bworoshye, imikorere myiza, hamwe nigisubizo cyihuse. Bafite uruhare runini mubice nkitumanaho, ubuvuzi, gutunganya inganda, no kumva / urwego. Ariko, mugihe muganira ku mikorere ya lazeri ya semiconductor, ikintu kimwe gisa nkicyoroshye ariko gikomeye cyane - icyiciro cyinshingano - akenshi kirengagizwa. Iyi ngingo yibira mubitekerezo, kubara, ibisobanuro, nubusobanuro bufatika bwinshingano zumurimo muri sisitemu ya semiconductor laser.

1. Inshingano yinshingano ni iki?

Inshingano yinshingano ni igipimo kitagira urugero gikoreshwa mugusobanura igipimo cyigihe laser iba iri muri "kuri" mugihe kimwe cyikimenyetso gisubiramo. Mubisanzwe bigaragazwa nkijanisha. Inzira ni: Inshingano Cycle = (Ubugari bwa Pulse/Igihe cya Pulse) × 100%. Kurugero, niba lazeri isohora 1-microsecond pulse buri microseconds 10, cycle yinshingano ni: (1 μs / 10 μs) × 100% = 10%.

2. Kuki Kuzenguruka Inshingano ari ngombwa?

Nubwo ari igipimo gusa, inzinguzingo yinshingano igira ingaruka ku buryo butaziguye imicungire yubushyuhe bwa laser, igihe cyo kubaho, imbaraga zisohoka, hamwe nuburyo rusange bwa sisitemu. Reka dusenye akamaro kayo:

Management Gucunga Ubushyuhe hamwe nubuzima bwose

Mubikorwa byinshyi byinshi, ibikorwa byinshyi bisobanura inshuro ndende "kuzimya" hagati yimisemburo, ifasha laser gukonja. Ibi ni ingirakamaro cyane cyane mubikorwa byimbaraga nyinshi, aho kugenzura urwego rwinshingano bishobora kugabanya imihangayiko yumuriro no kongera ubuzima bwibikoresho.

Imbaraga zisohoka hamwe nubugenzuzi bukomeye

Inshingano yo hejuru yinziza itanga umusaruro mwinshi ugereranije, mugihe urwego rwo hasi rugabanya imbaraga zisanzwe. Guhindura ingengabihe yinshingano zituma habaho guhuza neza ingufu zisohoka udahinduye icyerekezo cyimodoka.

③ Sisitemu Igisubizo no Guhindura Ibimenyetso

Mu itumanaho ryiza na sisitemu ya LiDAR, uruzinduko rwinshingano rugira uruhare runini mugihe cyo gusubiza hamwe na gahunda yo guhindura. Kurugero, muri lazeri ya pulseri iringaniye, gushiraho uburyo bukwiye bwinshingano zitezimbere echo yerekana ibimenyetso, byongera ibipimo byukuri hamwe ninshuro.

3. Gusaba Ingero zinshingano zinshingano

① LiDAR (Kumenya Laser no Kuringaniza)

Muri 1535nm ya lazeri iringaniye, module-yinshingano-ntoya, impinga-ndende ya pulse isanzwe ikoreshwa kugirango harebwe intera ndende ndetse n'umutekano w'amaso. Inshingano zinshingano zikunze kugenzurwa hagati ya 0.1% na 1%, kuringaniza imbaraga zo hejuru hamwe nibikorwa byiza, byiza.

Las Laser

Mubisabwa nko kuvura dermatologiya cyangwa kubaga laser, inzinguzingo zitandukanye zitera ingaruka zubushyuhe butandukanye nibisubizo byo kuvura. Inshingano ndende itera ubushyuhe burambye, mugihe urwego ruciriritse rushyigikira gukuraho ako kanya.

Processing Gutunganya ibikoresho byinganda

Mu gushyiramo lazeri no gusudira, inzinguzingo yinshingano igira ingaruka kuburyo ingufu zinjizwa mubikoresho. Guhindura inshingano zingirakamaro ni urufunguzo rwo kugenzura ubujyakuzimu no gusudira.

4. Nigute Guhitamo Inshingano Nziza?

Inzira nziza yinzira iterwa na progaramu yihariye n'ibiranga laser:

①Inshingano yo hasi (<10%)

Byiza cyane-impinga-ngufi, ngufi-pulse ikoreshwa nkurwego cyangwa ibimenyetso byerekana neza.

②Hagati yinshingano yo hagati (10% –50%)

Birakwiriye cyane-gusubiramo pulsed laser sisitemu.

③Inshingano Zisumbuyeho (> 50%)

Kwegera ibikorwa bikomeza (CW), bikoreshwa mubisabwa nka pompe optique hamwe n'itumanaho.

Ibindi bintu ugomba gusuzuma harimo ubushobozi bwo gukwirakwiza amashyuza, imikorere yumuzunguruko, hamwe nubushyuhe bwa laser.

5. Umwanzuro

Nubwo ari nto, inzinguzingo yinshingano ni urufunguzo rwo gushushanya muri sisitemu ya semiconductor. Ntabwo bigira ingaruka kumikorere gusa ahubwo binagira ingaruka ndende kandi ihamye ya sisitemu. Mu bihe biri imbere iterambere rya lazeri no kuyishyira mu bikorwa, kugenzura neza no gukoresha neza uburyo bwo kuzenguruka inshingano bizaba ingenzi mu kuzamura imikorere ya sisitemu no guhanga udushya.

Niba ufite ibibazo byinshi kubijyanye nigishushanyo mbonera cya laser cyangwa progaramu, wumve neza kugera cyangwa gusiga igitekerezo. Turi hano gufasha!
