Kusanthula kwa ma siginoloji akutali a laser ndi kukonza

Laserkusanthula ndi kukonza ma siginecha ozindikira mawu akutali
Kutanthauzira kwa phokoso lazizindikiro: kusanthula kwa ma siginecha ndikuwongolera kuzindikira kwamawu akutali a laser
M'bwalo lodabwitsa laukadaulo, kuzindikira kwamawu akutali kwa laser kuli ngati symphony yokongola, koma symphony iyi imakhalanso ndi "phokoso" lake - phokoso lazizindikiro. Mofanana ndi omvera aphokoso mosayembekezereka pa konsati, phokoso kaŵirikaŵiri limasokonezakuzindikira mawu a laser. Malinga ndi gwero, phokoso la kuzindikira kwamawu akutali a laser kumatha kugawidwa kukhala phokoso lomwe limayambitsidwa ndi chida choyezera kugwedezeka kwa laser palokha, phokoso lomwe limayambitsidwa ndi magwero ena amawu pafupi ndi cholinga choyezera kugwedezeka komanso phokoso lobwera chifukwa cha kusokonezeka kwa chilengedwe. Kuzindikira mawu akutali kumafunikira kupeza zizindikiro zamalankhulidwe zomwe zitha kuzindikirika ndi kumva kwa anthu kapena makina, ndipo phokoso losakanikirana lochokera kumadera akunja ndi makina ozindikira amachepetsa kumveka ndi kumveka kwa ma siginecha olankhulidwa, komanso kugawa ma frequency band. za phokoso izi zimachitika mwapang'onopang'ono ndi kagawo kakang'ono ka ma frequency band ya siginecha yamawu (pafupifupi 300 ~ 3000 Hz). Sizingatheke kusefedwa ndi zosefera zachikhalidwe, komanso kukonzanso zozindikirika zamalankhulidwe ndikofunikira. Pakalipano, ofufuza amaphunzira makamaka za kutulutsa phokoso la burodibandi losasunthika komanso phokoso lamphamvu.
Phokoso lakumbuyo kwa Broadband nthawi zambiri limakonzedwa ndi njira yoyezera kwakanthawi kochepa, njira yapansi panthaka ndi ma aligorivimu ena oletsa phokoso potengera ma siginecha, komanso njira zamakina zophunzirira zamakina, njira zophunzirira mozama ndi matekinoloje ena owonjezera mawu kuti alekanitse zidziwitso zamalankhulidwe kuchokera kumbuyo. phokoso.
Phokoso lachidziwitso ndilo phokoso la ma speckle lomwe likhoza kuyambitsidwa ndi mphamvu ya speckle pamene malo omwe amawunikira amasokonezedwa ndi kuwala kwa LDV yowunikira. Pakalipano, phokoso lamtunduwu limachotsedwa makamaka pozindikira malo omwe chizindikirocho chili ndi mphamvu yapamwamba yamphamvu ndikuyisintha ndi mtengo wonenedweratu.
Kuzindikira kwa mawu akutali kwa laser kumakhala ndi chiyembekezo chogwiritsa ntchito m'magawo ambiri monga kuthamangitsa, kuyang'anira njira zambiri, kuzindikira kulowerera, kufufuza ndi kupulumutsa, maikolofoni ya laser, ndi zina zotero. Tinganene kuti kafukufuku wamtsogolo wa kuzindikira kwa mawu akutali a laser adzakhazikitsidwa makamaka pa. (1) kuwongolera magwiridwe antchito a dongosolo, monga kukhudzika ndi chiwongolero cha phokoso, kukhathamiritsa njira yodziwira, magawo ndi mawonekedwe a makina ozindikira; (2) Limbikitsani kusinthika kwa ma aligorivimu pokonza ma siginolo, kuti ukadaulo wozindikira mawu a laser uzitha kutengera mtunda wosiyanasiyana wa miyeso, mikhalidwe ya chilengedwe ndi milingo yoyezera kugwedezeka; (3) Kusankha koyenera kwa miyeso yoyezera kugwedezeka, komanso kubweza kwafupipafupi kwa zizindikiro zamalankhulidwe zomwe zimayesedwa pazifukwa zomwe zimakhala ndi mawonekedwe osiyanasiyana oyankha pafupipafupi; (4) Sinthani dongosolo la dongosolo, ndikuwonjezeranso njira yodziwira

miniaturization, kusuntha komanso kuzindikira mwanzeru.
