LaserKuongorora kwechiratidzo chekutaura uye kugadzirisa
Iyo decoding yeruzha rwechiratidzo: kuongororwa kwechiratidzo uye kugadzirisa kwelaser kure kure kutaura kwekuona
Munhandare inoshamisa yetekinoroji, kuona kwelaser kure kutaura kwakafanana neinoyevedza symphony, asi symphony iyi inewo "ruzha" rwayo - ruzha rwechiratidzo. Kufanana nevateereri vane ruzha vasingakarirwi pakonzati, ruzha runowanzovhiringidza mukatiLaser kutaura kuona. Zvinoenderana nekwakabva, ruzha rwelaser kure kure kutaura chiratidzo chekucherechedza chinogona kukamurwa kuita ruzha rwakaunzwa nelaser vibration yekuyeresa chiridzwa pachayo, ruzha rwunounzwa nemamwe manzwi ari padhuze nekuyeresa kuyerwa uye ruzha rwunogadzirwa nekukanganiswa kwezvakatipoteredza. Kuonekwa kwekutaura kure-kure kunoda kuwana masaini ekutaura anogona kuzivikanwa nekunzwa kwevanhu kana michina, uye ruzha rwakavhengana rwakawanda kubva kunharaunda yekunze uye yekuona system inoderedza kunzwika uye kunzwisisika kwemasaini ekutaura akawanikwa, uye frequency band kugovera. yemheremhere iyi inopindirana neiyo huru frequency bhendi kugovera kwechiratidzo chekutaura (inenge 300 ~ 3000 Hz). Haikwanise kungosefa nemasefa echinyakare, uyezve kugadziridzwa kwemasaini ekutaura akaonekwa kunodiwa. Parizvino, vaongorori vanonyanya kudzidza dhinoising yeisiri-yakamira Broadband ruzha uye ruzha rwekukanganisa.
Broadband ruzha rwekumashure runowanzo gadziridzwa nepfupi-nguva spectrum estimation nzira, subspace nzira uye imwe ruzha kudzvinyirira algorithms yakavakirwa pakugadziriswa kwechiratidzo, pamwe nemaitiro echinyakare ekudzidza muchina, nzira dzekudzidza dzakadzika uye humwe hunyanzvi hwekusimudzira kutaura kuparadzanisa masaini ekutaura akachena kubva kumashure. noise.
Impulse noise ndiyo ruzha runogona kuunzwa neiyo dynamic speckle athari kana nzvimbo yekutarisa inokanganiswa nechiedza chekuona cheLDV yekuongorora system. Parizvino, rudzi urwu rweruzha runonyanya kubviswa nekuona nzvimbo iyo chiratidzo chine simba repamusoro uye kuchitsiva nehukoshi hwakafanotaurwa.
Laser kure kure kuona izwi rine tarisiro yekushandisa mune dzakawanda minda senge kubira, multi-mode monitoring, intrusion yekuona, kutsvaga nekununura, laser maikorofoni, etc. Zvinogona kufanotaurwa kuti ramangwana rekutsvaga maitiro ekuonekwa kwelaser kure izwi richanyanya kuenderana. (1) kuvandudza kuyerwa kwekuita kwehurongwa, sekunzwa uye chiratidzo-kune-ruzha chiyero, optimize yekuona maitiro, zvikamu uye chimiro cheiyo yekuona system; (2) Kuvandudza kuchinjika kwechiratidzo chekugadzirisa algorithms, kuitira kuti tekinoroji yekuona kwelaser kutaura inogona kuchinjika kune akasiyana kuyerwa madaro, mamiriro ezvakatipoteredza uye vibration kuyerwa kwezvinangwa; (3) Kuwedzera zvine musoro kusarudzwa kwezvinangwa zvekuyeresa, uye muripo wepamusoro-frequency yezviratidzo zvekutaura zvakayerwa pane zvinangwa zvine maitiro akasiyana-siyana emhinduro; (4) Kuvandudza sisitimu chimiro, uye wedzera optimize yekuona sisitimu kuburikidza

miniaturization, portability uye hungwaru yekuona maitiro.
