Tekinoroji yekuona ma photoelectric itsva (Chinoongorora chiedza cheAvalanche): Chitsauko chitsva mukuratidza zviratidzo zvechiedza zvisina simba
Mukutsvaga kwesainzi, kuona zviratidzo zvechiedza zvisina simba ndiyo kiyi yekuvhura minda yakawanda yesainzi. Munguva pfupi yapfuura, kubudirira kwesainzi kwakaunza shanduko huru mukuona zviratidzo zvechiedza zvisina simba.chinhu chinoona mafashamo emvuranhevedzano yakagadzirwa nechikwata chevatsvagiri vesainzi chinozivikanwa muChina, nekushanda kwacho kwakasiyana uye zvakanakira, ichavhura chitsauko chitsva chekuona zviratidzo zvechiedza zvisina simba.
Avalanchemudziyo wekuona fotozvigadzirwa zvakatevedzana, zvichienderana nepfungwa yekuwedzera mafashamo emvuraAPD, kukura kwacho kwakapetwa kagumi kusvika zana kupfuura kwePIN yakajairika photoelectric deep detector, ine kunzwa kwakanyanya, ruzha rwakaderera, kugona kuona zvakanaka uye zvimwe zvakanakira zvakakosha. Kubuda kwezvigadzirwa izvi kuchabatsira vaongorori kuona zviri nani nekuongorora zviratidzo zvechiedza zvisina simba, uye kukurudzira kudzika kwekutsvaga kwesainzi.
Zvinhu zvikuru zvezvigadzirwa izvi zvine ruzha rushoma, kuwedzera kwakanyanya uye fiber ye optical, sarudzo dzekubatanidza nzvimbo. Izvi zvinoreva kuti ingave iri nzvimbo yerabhoritari kana nzvimbo yakaoma yekunze, chigadzirwa ichi chinogona kuwana kuona kwakarurama kwechiratidzo che optical, zvichipa rutsigiro rwedata rwakavimbika kune vaongorori. Iyi tekinoroji itsva haingogadzirisi chete kugona kwekuona kwezviratidzo zve optical, asiwo inoderedza ruzha rwunobva mukuona uye inovandudza kururama kwekuona.
Zvikurukuru, huwandu hwemhinduro hunofukidza 300-1100nm uye 800-1700nm, ne3dB bandwidths inosvika 200MHz, 500MHz, 1GHz uye 10GHz. Aya magadzirirwo akasiyana-siyana uye ma parameter anogonesa chigadzirwa kuti chigone kuenderana nezvinodiwa zvakasiyana zvekutsvagisa kwesainzi, uye mashandisirwo akasiyana-siyana, anosanganisira kuona zviratidzo zve optical zvisina kusimba, kuona zviratidzo zve optical pulse nekukurumidza, uye kutaurirana kwe quantum.
Zvakakosha kutaura kuti chigadzirwa ichi chine photodiode yakavakirwa mukati, dunhu rekuwedzera ruzha rwakaderera, dunhu rekusimudzira ruzha reAPD, uye wavelength yekuona yezvikamu zvese zvezvigadzirwa inofukidza 300nm-1700nm. Dhizaini iyi inobvumira chigadzirwa kuwana kuona kwakanyanya, asiwo kuderedza ruzha zvinobudirira, kuvandudza kururama kwekuona. Pamusoro pezvo, zvimwe zvinhu zve optical fiber uye spatial coupling zvinoita kuti chigadzirwa chiwane kuona kwakarurama kwechiratidzo munzvimbo dzakasiyana-siyana dzakaoma.
Muchidimbu, kukura kwedambudziko irichinoona nezvemagetsiHapana mubvunzo kuti nhevedzano iyi ibudiriro huru muhunyanzvi hwekuona ma "photoelectric". Kubuda kwechigadzirwa ichi kunopa mukana mutsva wekuona masaini echiedza asina simba pasi rese. Tinotarisira kuti chigadzirwa ichi chichaita basa guru mukutsvagisa kwesainzi mune ramangwana, kukurudzira kufambira mberi kwesainzi, uye kubatsira zviri nani kukura kwevanhu.
