Ku Soo Biir Baraha Bulshada Si Aad U Hesho Qoraal Deg Deg Ah
Wuhan, Oktoobar 21, 2023- Xagga horumarka tignoolajiyada, Lumispot Tech waxay calaamad kale oo muhiim ah ku calaamadisay saloonkeeda mawduuca, "Iftiinka mustaqbalka Lasers," oo lagu qabtay Wuhan, oo ah magaalo qani ku ah muhiimada taariikhiga ah iyo dhaqanka. Salonkan, oo ah kii labaad ee taxanaheedii ka dib dhacdo guul ah oo ka dhacday Xi'an, waxay u adeegtay sidii madal lagu soo bandhigo guulaha la taaban karo ee Lumispot Tech iyo mashaariicda socda ee cilmi baarista iyo horumarinta.
Daahfurka Alaabta Hal-abuurka leh: "Bai Ze"Module Raging Laser
Iftiiminta saloonku waxay ka dhigtay hordhaca moduleka kala duwan ee leysarka "Bai Ze", hal-abuurnimadii ugu dambeysay ee Lumispot Tech ee tignoolajiyada laysarka. Badeecada soo socota ayaa qabatay dareenka warshadaha oo dhan sababtoo ah waxqabadkeeda gaarka ah iyo sareynta tignoolajiyada. Munaasabadan ayaa waxaa ka soo qaybgalay khubaro ka kala socotay Huazhong Optoelectronics, Jaamacadda Wuhan, iyo iskaashatooyin kala duwan oo ka kala socday warshadaha, kuwaas oo dhammaantood isugu soo baxay si ay uga tashadaan mustaqbalka mustaqbalka iyo codsiyada la taaban karo ee tignoolajiyada-laysarka.
Dejinta Heerarka Warshadaha Cusub
Moduleka "Bai Ze", oo marag u ah sida ay uga go'an tahay Lumispot Tech in ay hormood ka noqoto cilmi baarista iyo horumarinta, waxaa loogu talagalay in lagu daboolo shuruudaha cabbirka ee kala duwan, iyada oo bixisa xalal gaaban iyo qiimeyn ultra-dheer. Shirkaddu waxay samaysay horumarro la yaab leh oo ku saabsan soo saarista nidaamyo kala duwan oo leysarka lagu kalsoonaan karo oo kharash-ku-ool ah, gaar ahaan ka muuqda noocyo kala duwan oo alaabooyin ah oo awood u leh2km ilaa 12km cabbir.

Tignoolajiyada muhiimka ah ee lagu qaatay cutubka kala duwan ee "Bai Ze" ayaa ah mid ka tarjumaysa xoogga Lumispot Tech.
Qodobada soo socda ayaa si gaar ah u muuqda:
○ Is dhexgalka iyo yaraynta leysarka dhalooyinka erbium-doped (8mm × 8mm × 48mm):
Naqshaddan cusubi waxay si weyn u yaraynaysaa cabbirka laysarka iyadoo la ilaalinayo wax soo saarka tamarta sare. Dhinacan waxaa lagu xaqiijiyay cilmi-baarista Koch et al. (2007), kuwaas oo tilmaamay in laser-ka-yar-yar ay yihiin qayb muhiim ah oo ka mid ah hababka cabbiraadda dabaysha sababtoo ah waxay si weyn u yareeyn karaan isticmaalka tamarta guud ee nidaamka.
○Waqtiga saxda ah ee saxda ah iyo tignoolajiyada toosinta wakhtiga-dhabta ah (saxnimada wakhtiga: 60ps):
Soo bandhigida tignoolajiyadaani waxay u ogolaanaysaa wakhtiga qiiqa laysarka in si sax ah loo xakameeyo, taasoo lagu gaadhayo qiyaas sax ah oo ah heerka microsecond. Cilmi-baadhista Obland (2009) waxay muujinaysaa in tignoolajiyada is-habaynta wakhtiga-dhabta ah ay si toos ah u hagaajin karto goobaha qalabka iyadoo lagu saleynayo arrimaha deegaanka, hubinta saxnaanta natiijooyinka cabbirka.
○La qabsiga, tignoolajiyada kala duwan ee dariiqyada badan:
Farsamadani waxay si toos ah u dooran kartaa dariiqa kala duwan ee ugu wanaagsan, iyadoo si wax ku ool ah uga fogaanaysa khaladaadka cabbirka ee ay sababto xulashada dariiqa khaldan, gaar ahaan dhulalka qalafsan ama deegaanka leh caqabado badan (Milonni, 2009).
○Farsamada xakamaynta dhawaaqa iftiinka ee dhabarka dambe iyo APD tignoolajiyada ilaalinta iftiinka xoogga leh:
Isticmaalka wadajirka ah ee labadan teknoolajiyada kaliya maaha inay yareeyaan faragelinta iftiinka dambe ee natiijooyinka cabbirka, laakiin sidoo kale waxay ka ilaalisaa qalabka waxyeellada iftiinka xooggan, si loo helo xog la isku halleyn karo oo hoos timaada xaaladaha iftiinka kala duwan (Hall & Ageno, 1970).
○Naqshad fudud:
Module-ka guud waxa loo nashqadeeyay inuu noqdo mid fudud oo la qaadi karo, taasoo ka dhigaysa mid ku haboon mobilada ama codsiyada fog iyo kordhinta codsiga alaabta
Astaamaha Gaarka ah Dejinta Tilmaamo Cusub
Saxnaanta Gaarka ah: Qalabka isku-dhafan ee 100μJ erbium-doped laser galaas ayaa hubiya awoodaha cabbiraadda masaafada sare.
Qaadashada: Isagoo miisaankiisu ka yar yahay 35g, waxay dejisaa heer cusub oo dabacsanaan hawleed.
Waxtarka Tamarta: Qaabkeeda awood yar ayaa ka dhigaysa mid ku habboon codsiyada muddada dheer.

Codsiyada kala duwan ee Laser Fiber Pulsed
Muujinta dheeraadka ah ee hogaaminta warshadaha, Lumispot Tech waxay soo bandhigtay taxaneheeda lasers fiber pulsed, oo loogu talagalay waxqabadka iyo isafgaradka. Alaabooyinkani waxay u taagan yihiin qalab ku habboon codsiyada kala duwan, oo ay ku jiraan dareenka fog, la socodka muuqaalka muuqaalka, iyo dareenka garashada waddooyinka, iyo kuwo kale.
Horumarka laga helayo Alaabta Laser-ka ee Semiconductor
Ka go'naanta Lumispot Tech ee hal-abuurnimada waxay ku fidsan tahay shaqadeeda aaladaha leysarka semiconductor-ka awoodda sare leh iyo nidaamyada. Shaxda wax soo saarka ee shirkadu, oo lagu garto wax-qabadkeeda, waa natiijada 13 sano ee horumarka tignoolajiyada degdega ah iyo hal-abuurka.
Aragtida Khubarada
Salonka ayaa sidoo kale waxaa ka soo muuqday doodo dhaxal gal ah oo ay hogaaminayeen khubarada warshadaha. Soo bandhigida caanka ah waxaa ka mid ahaa cilmi-baarista Professor Liu Zhiming ee tignoolajiyada sahanka ee ay caawisay laysarka iyo ku xigeenka maareeyaha guud ee Gong Hanlu ee ku saabsan nidaamyada hawada laga qaado ee LiDAR.
Talaabo loo qaaday Mustaqbalka
Dhacdadani waxa ay hoosta ka xariiqday booska Lumispot Tech ee ah hormuudka tignoolajiyada laysarka, taas oo muujinaysa hab-fikirka hore ee horumarinta alaabta. Shirkaddu waxay sii waddaa inay u gogol xaarto horumarka mustaqbalka, iyada oo dejisa jaangooyooyin cusub oo warshadaha ah.
