Ho theknoloji ea sejoale-joale ea optoelectronic, lasers ea semiconductor e hlahella ka sebopeho sa bona se kopaneng, ts'ebetso e phahameng, le karabelo e potlakileng. Ba bapala karolo ea bohlokoa mafapheng a kang likhokahano, tlhokomelo ea bophelo bo botle, ts'ebetso ea indasteri, le ho utloa / ho laola. Leha ho le joalo, ha ho buisanoa ka tšebetso ea li-lasers tsa semiconductor, paramethara e le 'ngoe e bonahalang e le bonolo empa e le ea bohlokoa haholo - potoloho ea mosebetsi - hangata e hlokomolohuoa. Sengoliloeng sena se ikakhela ka setotsoana mohopolong, lipalo, litlamorao, le bohlokoa bo sebetsang ba potoloho ea mosebetsi ho litsamaiso tsa laser tsa semiconductor.
1. Duty Cycle ke Eng?
Duty cycle ke karo-karolelano e senang dimensionless e sebelisetsoang ho hlalosa karolo ea nako eo laser e leng boemong ba "ho" ka nako e le 'ngoe ea pontšo e iphetang. Hangata e hlalosoa e le peresente. Foromo ke: Duty Cycle=(Pulse Width/Pulse Period)×100%. Mohlala, haeba laser e ntša 1-microsecond pulse ka metsotsoana e meng le e meng e 10, potoloho ea mosebetsi ke: (1 μs/10 μs)×100%=10%.
2. Ke Hobane'ng ha Mosebetsi oa Cycle o le Bohlokoa?
Leha e le karo-karolelano feela, potoloho ea mosebetsi e ama ka kotloloho taolo ea mocheso oa laser, nako ea bophelo, matla a tlhahiso, le moralo oa sistimi ka kakaretso. Ha re hlalose bohlokoa ba eona:
① Taolo ea Thermal le Sesebelisoa sa Bophelo Bohle
Lits'ebetsong tse phahameng tsa maqhubu, potoloho e tlase ea mosebetsi e bolela nako e telele ea "ho tima" lipakeng tsa maqhubu, e thusang laser hore e phomole. Sena se na le molemo ka ho khetheha lits'ebetsong tsa matla a phahameng, moo ho laola potoloho ea mosebetsi ho ka fokotsang khatello ea mocheso le ho lelefatsa bophelo ba sesebelisoa.
② Matla a Output le Optical Intensity Control
Mosebetsi o phahameng oa potoloho o fella ka tlhahiso e kholo ea karolelano ea optical, ha potoloho e tlase ea mosebetsi e fokotsa matla a tloaelehileng. Ho fetola potoloho ea mosebetsi ho lumella ho hlophisoa hantle ha matla a tsoang ntle le ho fetola lebelo le phahameng la koloi.
③ Karabelo ea Sisteme le Pontšo ea Lipontšo
Litabeng tsa puisano tsa optical le LiDAR, potoloho ea mosebetsi e ama ka kotloloho nako ea karabelo le merero ea ho feto-fetoha ha maemo. Mohlala, ho pulsed laser ho tloha, ho beha potoloho e nepahetseng ea mosebetsi ho ntlafatsa ho lemoha ha lets'oao la echo, ho ntlafatsa ho nepahala ha tekanyo le khafetsa.
3. Mehlala ea Kopo ea Mosebetsi oa Cycle
① LiDAR (Tlhahlobo ea Laser le ho Rala)
Ka har'a li-module tsa laser tse 1535nm, tlhophiso e tlase-tlase, e phahameng-tlhōrō ea pulse e sebelisoa ka tloaelo ho netefatsa hore ho fumanoa nako e telele le ho sireletseha ha mahlo. Lipotoloho tsa mosebetsi li atisa ho laoloa pakeng tsa 0.1% le 1%, ho leka-lekanya matla a phahameng a phahameng ka ts'ebetso e sireletsehileng, e pholileng.
② Li-Laser tsa Bongaka
Lits'ebetsong tse joalo ka kalafo ea dermatological kapa opereishene ea laser, lipotoloho tse fapaneng tsa mesebetsi li baka litlamorao tse fapaneng tsa mocheso le liphetho tsa kalafo. Potoloho e phahameng ea mosebetsi e baka ho futhumatsa ho tsitsitseng, ha potoloho e tlase ea mosebetsi e ts'ehetsa ho tsoa ha pulsed hang hang.
③ Ts'ebetso ea Lintho tsa Indasteri
Ho tšoaea laser le ho cheselletsa, potoloho ea mosebetsi e ama tsela eo matla a kenngoa ka har'a thepa. Ho fetola potoloho ea mosebetsi ke senotlolo sa ho laola botebo ba ho betla le ho kenella ha welding.
4. Joang ho Khetha Right Duty Cycle?
Potoloho e nepahetseng ea mosebetsi e ipapisitse le ts'ebeliso e ikhethileng le litšobotsi tsa laser:
①Phaello e Tlase (<10%)
E loketse lits'ebetso tse phahameng haholo, tse khutsufalitsoeng joalo ka ho tšoaea kapa ho tšoaea ka nepo.
②Medium Duty Cycle (10%–50%)
E loketse litsamaiso tsa laser tsa pulsed tse pheta-phetoang.
③High Duty Cycle (>50%)
Ts'ebetso e ntseng e atamela e tsoelang pele (CW), e sebelisoang lits'ebetsong tse kang ho pompa ka mahlo le likhokahano.
Lintlha tse ling tse lokelang ho nahanoa li kenyelletsa bokhoni ba ho qhala ha mocheso, ts'ebetso ea potoloho ea mokhanni, le botsitso ba mocheso oa laser.
5. Qetello
Leha e le nyane, potoloho ea mosebetsi ke paramente ea bohlokoa ea moralo lits'ebetsong tsa laser tsa semiconductor. Ha e ame feela tlhahiso ea ts'ebetso empa hape le botsitso ba nako e telele le ho tšepahala ha tsamaiso. Ho nts'etsopele le ts'ebeliso ea laser nakong e tlang, taolo e nepahetseng le ts'ebeliso e bonolo ea potoloho ea mosebetsi e tla ba tsa bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea sistimi le boqapi bo lumellang.
Haeba u na le lipotso tse ling mabapi le moralo kapa lits'ebetso tsa laser, ikutloe u lokolohile ho fana ka maikutlo kapa ho siea maikutlo. Re mona ho tla thusa!
