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 kwamawu akutali kumafunikanso kupeza zizindikiro zamalankhulidwe zomwe zitha kuzindikirika ndi kumva kwa anthu kapena makina, ndipo phokoso losakanikirana lochokera kunja ndi njira yodziwira zimachepetsa kumveka komanso kumveka kwa ma siginecha amalankhulidwe omwe adapezedwa, ndipo ma frequency band kugawa kwa maphokosowa kumangochitika mwangozi ndi gawo lalikulu la ma frequency band la siginecha yolankhulira (pafupifupi 30000 H0). Sizingatheke kusefedwa ndi zosefera zachikhalidwe, komanso kukonzanso zozindikirika zamalankhulidwe ndikofunikira. Pakali pano, ofufuza makamaka amaphunzira kutulutsa phokoso la burodibandi losakhazikika komanso phokoso lamphamvu.
Phokoso lakumbuyo kwa Broadband nthawi zambiri limakonzedwa ndi njira yanthawi yochepa yoyerekeza sipekitiramu, 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 koyera ndi phokoso lakumbuyo.
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 mwayi wogwiritsa ntchito m'magawo ambiri monga kuthamangitsa, kuyang'anira njira zingapo, kuzindikira kulowerera, kusaka ndi kupulumutsa, maikolofoni ya laser, ndi zina zotero. Tinganene kuti m'tsogolomu kafukufuku wa laser azitha kuzindikira mawu akutali adzatengera (1) kukonza kayezedwe ka makina, monga kukhudzika ndi chiŵerengero cha phokoso ndi phokoso, kukhathamiritsa njira yodziwira, zipangizo ndi makina; (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.
