Kuongorora nekugadzirisa masaini ekuona kutaura kweLaser kure

Laserkuongorora nekugadzirisa zviratidzo zvekutaura zviri kure
Kugadziriswa kweruzha rwechiratidzo: kuongorora kwechiratidzo uye kugadziriswa kwekuona kutaura kuri kure nelaser
Munzvimbo inoshamisa ye tekinoroji, kuona kutaura kuri kure nelaser kwakafanana nesymphony yakanaka, asi iyi symphony inewo "ruzha" rwayo - ruzha rwechiratidzo. Kufanana nevateereri vane ruzha rusingatarisirwi pakonzati, ruzha runowanzo kanganisa mukatikuona kutaura kwelaser. Sekureva kwemunhu ari kuburitsa mashoko, ruzha rwekuona zviratidzo zvekutaura zviri kure nelaser runogona kukamurwa kuita ruzha rwunounzwa nechishandiso chekuyera vibration chelaser, ruzha rwunounzwa nemamwe manzwi ari pedyo nechinoyerwa vibration uye ruzha rwunounzwa nekukanganiswa kwezvakatipoteredza. Kuona kutaura kure kunoda kuwana zviratidzo zvekutaura zvinogona kuzivikanwa nekunzwa kwevanhu kana michina, uye ruzha rwakawanda rwakasanganiswa kubva kunze uye sisitimu yekuona zvinoderedza kunzwika nekunzwisisika kwezviratidzo zvekutaura zvinowanikwa, uye kugoverwa kwebhendi rema frequency kweruzha urwu kunoenderana nekugoverwa kukuru kwebhendi rema frequency kwechiratidzo chekutaura (inenge 300 ~ 3000 Hz). Harugone kungosefetwa nema filters echinyakare, uye kugadziriswa kwakawanda kwezviratidzo zvekutaura zvinoonekwa kunodiwa. Parizvino, vaongorori vanodzidza zvakanyanya nezvekubvisa ruzha rwe broadband noise uye impact noise.
Ruzha rwekumashure rweBroadband runowanzo gadziriswa nenzira yekufungidzira kwenguva pfupi, nzira yesubspace uye mamwe maalgorithms ekudzora ruzha zvichibva pakugadzirisa masaini, pamwe nenzira dzechinyakare dzekudzidza kwemuchina, nzira dzekudzidza zvakadzama uye mamwe matekinoroji ekuvandudza kutaura kuti aparadzanise masaini ekutaura akachena kubva kunzwi rekumashure.
Ruzha rwekuvhunduka (impulse noise) ruzha rwema speckle runogona kuunzwa ne dynamic speckle effect kana nzvimbo ye detection target yakakanganiswa ne detection light ye LDV detection system. Parizvino, rudzi urwu rweruzha runonyanya kubviswa nekuona nzvimbo iyo chiratidzo chine simba rakawanda uye kuchitsiva ne fungidziro.
Kuona izwi riri kure neLaser kune mikana yekushandisa munzvimbo dzakawanda dzakadai sekubata, kutarisa kwemaitiro akawanda, kuona kupinda, kutsvaga nekununura, maikorofoni yelaser, nezvimwewo. Zvinogona kufanotaurwa kuti maitiro ekutsvaga eramangwana ekuona izwi riri kure nelaser achave akavakirwa zvakanyanya pa (1) kuvandudza mashandiro ekuyera kwesystem, senge sensitivity uye signal-to-noise ratio, kugadzirisa maitiro ekuona, zvikamu uye chimiro chesystem yekuona; (2) Kuvandudza kuchinjika kwemaalgorithms ekugadzirisa masaini, kuitira kuti tekinoroji yekuona kutaura kwelaser igone kuchinjika kumatanho akasiyana ekuyera, mamiriro ekunze uye zvinangwa zvekuyera vibration; (3) Kusarudzwa kwakaringana kwezvinangwa zvekuyera vibration, uye kubhadharwa kwezviratidzo zvekutaura zvakayerwa pazvinangwa zvine hunhu hwakasiyana hwekupindura kwemafrequency; (4) Kuvandudza chimiro chesystem, uye kuwedzera kugadzirisa system yekuona kuburikidza

miniaturization, kutakurwa uye maitiro ekuona akangwara.
