Kusanthula ndi kukonza chizindikiro cha kuzindikira mawu akutali pogwiritsa ntchito laser

LaserKusanthula ndi kukonza zizindikiro zozindikira mawu patali
Kuzindikira phokoso la chizindikiro: kusanthula chizindikiro ndi kukonza kuzindikira kwa kulankhula kwakutali kwa laser
Mu gawo lodabwitsa la ukadaulo, kuzindikira mawu akutali pogwiritsa ntchito laser kuli ngati symphony yokongola, koma symphony iyi ilinso ndi "phokoso" lake - phokoso la chizindikiro. Monga omvera omwe amangokhalira phokoso pa konsati, phokoso nthawi zambiri limasokonezakuzindikira mawu pogwiritsa ntchito laserMalinga ndi gwero, phokoso la kuzindikira chizindikiro cha kulankhula chakutali cha laser lingagawidwe m'magulu awiri: phokoso lomwe limayambitsidwa ndi chipangizo choyezera kugwedezeka kwa laser, phokoso lomwe limayambitsidwa ndi magwero ena a mawu pafupi ndi cholinga choyezera kugwedezeka ndi phokoso lomwe limapangidwa ndi kusokonezeka kwa chilengedwe. Kuzindikira mawu patali pamapeto pake kumafunika kupeza zizindikiro zolankhulira zomwe zitha kuzindikirika ndi kumva kwa anthu kapena makina, ndipo phokoso losiyanasiyana lochokera ku chilengedwe chakunja ndi makina ozindikira limachepetsa kumveka ndi kumveka kwa zizindikiro zolankhulira zomwe zapezedwa, ndipo kufalikira kwa ma frequency band a phokosoli kumachitika molumikizana ndi kufalikira kwakukulu kwa ma frequency band a chizindikiro cholankhulira (pafupifupi 300 ~ 3000 Hz). Sizingangosefedwe ndi zosefera zachikhalidwe, ndipo kukonza kwina kwa zizindikiro zolankhulira zomwe zapezeka kumafunika. Pakadali pano, ofufuza amaphunzira makamaka za kuchepetsa phokoso la broadband losakhazikika komanso phokoso lokhudza kukhudzidwa.
Phokoso lakumbuyo la Broadband nthawi zambiri limakonzedwa pogwiritsa ntchito njira yowerengera ma spectrum afupiafupi, njira ya subspace ndi ma algorithms ena oletsa phokoso kutengera njira yogwiritsira ntchito ma signal, komanso njira zachikhalidwe zophunzirira makina, njira zophunzirira mozama ndi ukadaulo wina wowonjezera mawu kuti alekanitse zizindikiro zoyera za mawu ndi phokoso lakumbuyo.
Phokoso la Impulse ndi phokoso la speckle lomwe lingayambitsidwe ndi mphamvu ya speckle pamene malo a chinthu chodziwira asokonezedwa ndi kuwala kozindikira kwa dongosolo lozindikira la LDV. Pakadali pano, phokoso lamtunduwu limachotsedwa makamaka pozindikira malo omwe chizindikirocho chili ndi mphamvu yayikulu ndikuchisintha ndi mtengo wolosera.
Kuzindikira mawu akutali kwa laser kuli ndi mwayi wogwiritsa ntchito m'magawo ambiri monga kutsekereza, kuyang'anira njira zambiri, kuzindikira kulowerera, kusaka ndi kupulumutsa, maikolofoni ya laser, ndi zina zotero. Zingathe kunenedweratu kuti kafukufuku wamtsogolo wofufuza mawu akutali kwa laser udzadalira kwambiri (1) kukonza magwiridwe antchito a makina, monga kukhudzidwa ndi chiŵerengero cha chizindikiro ndi phokoso, kukonza njira yodziwira, zigawo ndi kapangidwe ka makina odziwira; (2) Kulimbitsa kusinthasintha kwa ma algorithms opangira ma signal, kuti ukadaulo wozindikira mawu a laser uzitha kusintha mtunda wosiyanasiyana, mikhalidwe yachilengedwe ndi zolinga zoyezera kugwedezeka; (3) Kusankha bwino zolinga zoyezera kugwedezeka, komanso kulipira zizindikiro zolankhulira pafupipafupi zomwe zimayesedwa pa zolinga zomwe zili ndi mawonekedwe osiyanasiyana oyankha pafupipafupi; (4) Kukonza kapangidwe ka makina, ndikuwonjezera kukonza makina odziwira kudzera

Kuchepetsa mphamvu ya chipangizo, kusunthika mosavuta komanso njira yodziwira zinthu mwanzeru.
