Ubuchwepheshe bokutholwa kwenkulumo ye-Laser Remote Speech
I-laserUkutholwa Kwenkulumo Ekude: Kwembula ukwakheka kohlelo lokutholwa

Umfutho we-laser omncane udansa kahle emoyeni, usesha buthule imisindo ekude, umgomo we-futuristic Technological "umlingo" u-esoteric futhi ugcwele i-charm. Namuhla, ake siphakamise iveli kulobu buchwepheshe obumangalisayo futhi bahlole ukwakheka kwalo okuhle nemigomo. Umgomo wokutholwa kwezwi okude ye-laser kukhonjiswa kuMfanekiso 1 (a). Uhlelo lokuthola usizo lwe-laser Remote Voice lwenziwe ngohlelo lokulinganisa lwe-laser vibration kanye nelitshe elingabambisanayo lokulinganisa. Ngokusho kwemodi yokutholwa kokubuya kokukhanya, uhlelo lokutholwa lungahlukaniswa ngohlobo olungaphazamisi nohlobo lokuphazamiseka, futhi umdwebo we-schematic uboniswa ngokulandelana kuMfanekiso 1 (B) no (c).

一. Ukutholwa kokutholwa kokungaphazanyiswa kokungaphazanyiswa kungumlingisi oqondile kakhulu wabangane, ngokusebenzisa i-laser irradiation of the group grade, ngesithombe esibonakalayo se-azimuth esinqunyelwe ukulinganisa okuhlosiwe kwe-acoustic vibration, bese uqonde ngqo "ukuze uthole ukutholwa okukude kwe-acoustic. Ngokwesakhiwo sokwamukelaI-PhotoDETETETETECETETET, uhlelo olungaphazamisi lungahlukaniswa luhlobo lwamaphoyinti owodwa nohlobo lwe-array. The core of the single-point structure is the “reconstruction of the acoustic signal”, that is, the surface vibration of the object is measured by measuring the change of the detector's detection light intensity caused by the change of the return light orientation. Isakhiwo sephuzu elilodwa sinezinzuzo zezindleko eziphansi, ukwakheka okulula, isilinganiso esiphakeme sesampula kanye nokwakhiwa kabusha kwesikhathi se-acoustic ngokuya ngobudlelwano be-detector pertection, ngakho-ke kuvinjelwe ukusetshenziswa kohlelo lokutholwa kwe-linye. Isakhiwo se-Array sakha kabusha ukudlidliza komhlaba kwelitshe ngokusebenzisa i-algorithm yesithombe se-speckle, ukuze uhlelo lokulinganisa lokudlidliza lunokuvumelana okuqinile endaweni enzima, futhi kunokunemba okuphezulu nokuzwela.

二. Uhlelo lokutholwa kokuxhaphaza luhlukile ekuboneni kokutholwa okungaphazanyiswa, ukutholwa kokuphazamiseka kune-charm eqondile engaqondile, i-assuct okuhlosiwe lapho ushintsha khona i-assuction, ukuguquguquka kobuchwepheshe bokulinganisa ukukala ukulinganiswa kwe-frequency shift. Njengamanje, ubuchwepheshe bokutholwa kwe-interferometric athuthukisiwe bungahlukaniswa ngezinhlobo ezimbili ngokuya ngomgomo we-Laser Doppler Vivingrate Technology kanye nendlela ye-laser yokuzixubisa yokuphazamiseka ngokususelwa ekutholweni kwesiginali okukude kwe-acoustic. Indlela yokulinganisa ye-Laser Doppler isuselwa emphumeleni we-doppler ye-laser ukuthola isinali yomsindo ngokulinganisa i-Doppler Frequency Shift ebangelwa ukudlidliza kwento eqondiwe. Ubuchwepheshe be-Laser bokuzihlanganisa bokuzihlanganisa buvumelana nokufuduka, isivinini, ukudlidliza kanye nebanga lelitshe ngokuvumela ukukhanya kokukhanya okuveziwe kwelitshe elikude ukufaka kabusha i-laser resonator futhi kubangele ukuguqulwa kwe-laser field amplitude kanye nemvamisa. Izinzuzo zayo zilele ngosayizi omncane kanye nokuzwela okuphezulu kohlelo lokulinganisa lwe-vibration, kanyeI-Laser yamandla ephansiingasetshenziswa ukuthola isinali ye-Remote Sound. Uhlelo lokulinganisa lokuzixubeka lwe-lasency-shift lwe-lasecy

Njengendlela ewusizo nobuchwepheshe obusebenzayo, umlingo we-laser "play" play "play disete inkulumo awukwazi kuphela emkhakheni wokutholwa, emkhakheni wokutholwa okukhohlisayo futhi unobuchwepheshe obuhle kakhulu - ubuchwepheshe be-Laser Ukuqondanisa. Lobu buchwepheshe bungafezekisa izilinganiso ze-Level Level Level ezingenisiwe ngaphakathi, ezakhiweni zehhovisi nakwezinye izindawo zodonga lwengilazi yengilazi, futhi idivaysi eyodwa ingavikela ngempumelelo ijubane lenkomfa elinamamitha ayi-10, ngokunemba okuphezulu kwamanani wokuthola amamitha ayi-90, kanye nokunemba okuphezulu komsebenzi wesikhathi eside ozinzile. Ubuchwepheshe be-Laser Ukuntweza kwe-countermeation bunganikeza isiqinisekiso esinamandla sokuphepha kwemininingwane yabasebenzisi emahhovisi asemkhakheni asemqoka nakwezinye izimo.
