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. Ubhaqo lwentetho olukude ekugqibeleni lufuna ukufumana imiqondiso yentetho enokuthi iqondwe ngokuva kwabantu okanye ngoomatshini, kunye nengxolo eninzi exubeneyo evela kwindawo yangaphandle kunye nenkqubo yobhaqo iya kunciphisa ukuviwa nokuqondakala kwemiqondiso yentetho efunyenweyo, kunye nokuhanjiswa kwebhendi rhoqo. yale ngxolo ngokuyinxenye ngokuhambelanayo nokusasazwa kwebhendi yefrikhwensi yomqondiso wentetho (malunga ne-300 ~ 3000 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 yindlela yoqikelelo lwexesha elifutshane, indlela yesithuba esisezantsi kunye nezinye iindlela zokucinezela ingxolo esekwe ekusetyenzweni komqondiso, kunye neendlela zokufunda zoomatshini bemveli, iindlela zokufunda nzulu kunye nobunye ubugcisa bokuphucula intetho ukwahlula imiqondiso yentetho esulungekileyo ukusuka ngasemva. ingxolo.
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.
Ubhaqo lwelizwi olukude ngeLaser lunamathuba osetyenziso kwiindawo ezininzi ezinje ngokungenelela, ukujonga iindlela ezininzi, ukubhaqwa kokungena, ukukhangela nokuhlangula, imakrofoni yelaser, njl. njl. (1) ukuphucula ukusebenza komlinganiselo wenkqubo, njengobuntununtunu kunye ne-signal-to-noise ratio, ukuphucula indlela yokufumanisa, amacandelo kunye nesakhiwo senkqubo yokufumanisa; (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.
