Uhlalutyo lwesignali yokubona intetho ekude yeLaser kunye nokuqhubekeka

ILaserUhlalutyo lophawu lophawu lwentetho olukude kunye nokuqhubekeka
Ukuchazwa kwengxolo yomqondiso: uhlalutyo lwesignali kunye nokusetyenzwa kobhaqo lwentetho olukude ngelaser
Kwibala letekhnoloji elimangalisayo, ukubonwa kwentetho ekude nge-laser kufana ne-symphony entle, kodwa le symphony ikwanayo "ingxolo" - ingxolo yomqondiso. Njengabaphulaphuli abanengxolo engalindelekanga ekonsathini, ingxolo idla ngokuphazamisaukubhaqwa kwentetho yelaser. Ngokomthombo, ingxolo ye-laser yokufumanisa umqondiso wentetho ekude ingohlulwa ngokurhabaxa ibe yingxolo eyaziswa sisixhobo somlinganiselo we-laser vibration ngokwayo, ingxolo eyaziswa yeminye imithombo yesandi kufutshane nethagethi yomlinganiselo wokungcangcazela kunye nengxolo eyenziwa kukuphazamiseka kokusingqongileyo. Ukubhaqwa kwentetho ekude ekugqibeleni kufuna ukufumana imiqondiso yentetho enokuthi iqondwe ngokuva kwabantu okanye ngoomatshini, kunye nezandi ezininzi ezixubeneyo ezivela kwindawo yangaphandle kunye nenkqubo yokufumanisa iya kunciphisa ukuva kunye nokuqondakala kwemiqondiso yentetho efunyenweyo, kwaye ukuhanjiswa kwebhendi ye-frequency yale ngxolo ngokuyinxenye ngokuhambelanayo kunye nokusabalalisa ibhendi ye-frequency engundoqo yesignali yentetho (malunga ne-3000 H0000 HZ). Ayinakuhluzwa ngokulula ngezihluzo zemveli, kwaye ukuqhubela phambili kwemiqondiso yentetho echongiweyo iyafuneka. Okwangoku, abaphandi bafunda ubukhulu becala ukudityaniswa kwengxolo yebroadband engatshintshiyo kunye nengxolo yempembelelo.
Ingxolo yangasemva yebroadband isenziwa ngokubanzi ngendlela yoqikelelo lwexesha elifutshane, indlela ye-subspace kunye nezinye ii-algorithms zokucinezela ingxolo esekwe ekusetyenzweni komqondiso, kunye neendlela zokufunda zoomatshini eziqhelekileyo, iindlela zokufunda nzulu kunye nobunye ubuchwepheshe bokuphucula intetho ukwahlula imiqondiso yentetho esulungekileyo kwingxolo yangasemva.
Ingxolo ye-Impulse yingxolo ye-speckle enokuthi ingeniswe yimpembelelo ye-speckle eguquguqukayo xa indawo yokukhangela ekujoliswe kuyo iphazamiseka kukukhanya kwenkqubo yokufumanisa i-LDV. Okwangoku, olu hlobo lwengxolo lususwa ikakhulu ngokubona indawo apho umqondiso unencopho yamandla aphezulu kwaye uyitshintshe ngexabiso eliqikelelweyo.
Ukubhaqwa kwelizwi elikude ngeLaser kunemibono yesicelo kwiinkalo ezininzi ezinje ngokungenelela, ukujonga iindlela ezininzi, ukubhaqwa kokungena, ukukhangela nokuhlangula, imakrofoni yelaser, njl. njl (2) Ukuphucula ukulungelelaniswa kwe-algorithms yokucwangcisa umqondiso, ukwenzela ukuba iteknoloji yokufumanisa intetho ye-laser ikwazi ukulungelelanisa imigama eyahlukeneyo yokulinganisa, iimeko zokusingqongileyo kunye neethagethi zokulinganisa ukungcangcazela; (3) Ukukhetha okunengqiqo ngakumbi kwiithagethi zokulinganisa ukungcangcazela, kunye nembuyekezo yesantya esiphezulu semiqondiso yentetho elinganiswe kwiithagethi ezineempawu ezahlukeneyo zokuphendula rhoqo; (4) Ukuphucula ubume benkqubo, kunye nokwandisa ngakumbi inkqubo yokubona ngokusebenzisa

miniaturization, ukuphatheka kunye nenkqubo yokubhaqa ngobukrelekrele.
