Laser kugadzirisa optical system mhinduro
Kutsunga kwekugadziriswa nelaserMhinduro ye optical system inoenderana nemamiriro ezvinhu chaiwo ekushandisa. Mamiriro akasiyana anotungamira kune mhinduro dzakasiyana dze optical system. Kuongorora kwakananga kunodiwa kune mamwe mashandisirwo. Optical system inoratidzwa muMufananidzo 1:

Nzira yekufunga ndeiyi: zvinangwa zvemaitiro chaiwo -laserhunhu - dhizaini yehurongwa hwe optical system - kuzadzikiswa kwechinangwa chekupedzisira. Inotevera minda yakasiyana-siyana yekushandisa:
1. Munda wekugadzirisa zvinhu zvishoma nemazvo (kumaka, kucheka, kuboora, kucheka nemazvo, nezvimwewo) Maitiro akajairika mumunda wekugadzirisa zvinhu zvishoma nemazvo ndeyekugadzirisa zvinhu zvakaita sesimbi, ceramics, negirazi, zvakaita sekuisa logo pamafoni, medical stents, maburi madiki ema nozzles ekuisa mafuta mugasi, nezvimwewo. Chinodiwa chikuru mukugadzirisa ndeichi: chekutanga, chinofanira kusangana nechiedza chidiki chakatarisana, simba rakawanda kwazvo, uye nzvimbo diki yekupisa, nezvimwewo. Pamashandisirwo nezvinodiwa pamusoro apa, kusarudzwa nekugadzirwa kwemanyuko echiedza chelasernezvimwe zvikamu zvinoitwa.
a. Kusarudzwa kweLaser: Laser yakasimba ye ultraviolet/green (nanosecond) kana ultrafast laser (picosecond, femtosecond) inonyanya kukonzerwa nezvikonzero zviviri. Chimwe ndechekuti wavelength inoenderana nenzvimbo yechiedza chakatarisana, uye kazhinji wavelength pfupi inosarudzwa. Chechipiri ndechekuti picosecond/femtosecond pulses dzine hunhu hwe "cold processing", uye simba rinopedzwa kugadzirwa kwemafuta asati apararira, zvichiita kuti cold processing ibudirire. Kazhinji, sosi yechiedza chelaser ine spatial light output inosarudzwa, ine beam quality factor M2 kazhinji iri pasi pe1.1, ine beam quality yepamusoro.
b. Sisitimu yekuwedzera danda uye sisitimu yekuunganidza danda zvinowanzoshandisa malenzi ekuwedzera danda anochinja-chinja (2X - 5X), vachiedza kuwedzera dhayamita yedanda zvakanyanya sezvinobvira. Dhayamita yedanda inoenderana zvakanyanya nenzvimbo yechiedza yakatarisana, uye dhizaini yekuwedzera danda reGalilean inowanzo shandiswa.
c. Sisitimu yekutarisa inowanzo shandisa malenzi eF-Theta anoshanda zvakanyanya (ekuskena) kana malenzi ekutarisa ane telecentric. Kureba kwefocal kunoenderana nenzvimbo yechiedza chakanangana, uye kazhinji malenzi mapfupi efocal field (akadai se f = 50mm, 100mm) anoshandiswa. Sezvakaratidzwa muMufananidzo 1: Kazhinji, lenzi yemunda inoshandisa boka relenzi rine zvinhu zvakawanda (nhamba yemalenzi ≥ 3), iyo inogona kuwana nzvimbo yakakura yekuona, aperture yakakura, uye zviratidzo zvishoma zvekusagadzikana. Malenzi ekuona pano ese anofanirwa kufunga nezve chiyero chekukuvadzwa kwelaser.
d. Sisitimu yekutarisa maoptical yeCoaxial: Musisitimu yekuona, sisitimu yekuona maoxial (CMOS) inowanzo batanidzwa kuti ikwanise kuiswa zvakanaka uye itarisire mashandiro ekugadzirisa panguva chaiyo.
2. Kugadziriswa kwezvinhu zvikuru. Maitiro akajairika ekushandiswa kwezvinhu zvikuru anosanganisira kucheka zvinhu zvemapepa emotokari, kusungirirwa kwesimbi dzemuviri wengarava, uye kusungirirwa kwemabhatiri. Maitiro aya anoda simba rakawanda, kugona kupinda mukati zvakanyanya, kushanda zvakanaka, uye kugadzikana kwekugadzirisa.
3. Kugadzira zvinhu zvinowedzerwa nelaser (3D printing) uye kugadzira zvinhu zvinowedzerwa nelaser (3D printing) uye mashandisirwo ezvipfeko zvinofukidza zvinhu zvinowanzo sanganisira maitiro anotevera: kudhinda simbi muaerospace, kugadzirisa simbi dzeinjini, nezvimwewo.
Kusarudzwa kwezvikamu zvikuru ndekwekuti:
a. Kusarudzwa kweLaser: Kazhinji,ma-fiber laser ane simba guruzvinosarudzwa, zvine simba rinowanzo pfuura 500W.
b. Kuumba danda: Sisitimu iyi ye optical inofanira kuburitsa mwenje wakatsetseka, saka kugadzira danda ndiyo tekinoroji huru, uye inogona kuwanikwa uchishandisa zvinhu zvinoburitsa chiedza.
c. Sisitimu yekutarisa: Magirazi uye dynamic focus ndizvo zvinodiwa mumunda wekudhinda we3D. Panguva imwe chete, lenzi yekuskena inofanirwa kushandisa dhizaini ye telecentric yechinhu kuti ive nechokwadi chekuti processing ye edge ne centre inoenderana.
