HAMAMATSU, Japan, Nyamavhuvhu 25, 2021 - Hamamatsu Photonics uye National Institute of Advanced Industrial Science uye Technology (AIST) muTokyo vakabatana pane-optical, inotakurika gasi yekutarisa system yekufungidzira kuputika kwemakomo nehupamhi hwekunzwisisa. Kunze kwekupa yakagadzikana, yenguva refu yekutarisa magasi anoputika padyo nemakoropu anoputika, iyo inotakurika analyzer inogona zvakare kushandiswa kuona huturu hwegasi hunodonha mumakemikari zvigadzirwa uye mapaipi uye zviyero zvemuchadenga.

Iyo sisitimu ine miniaturized, wavelength-yakatsvairwa quantum cascade laser (QCL) yakagadzirwa naHamamatsu. Pakatenderedza 1 / 150th saizi yeiyo yapfuura QCLs, iyo laser ndiyo diki diki wavelength-yakatsvairwa QCL. Iyo yekutyaira sisitimu yeiyo gasi yekutarisa system, yakagadziridzwa neAIST, inobvumidza iyo diki QCL kuti iiswe mukati isingaremi, inotakurika vaongorori iyo inogona kutakurwa chero kupi.
Yepasi padiki wavelength-yakatsvairwa QCL inongova 1 / 150th saizi yeakapfuura wavelength-yakatsvairwa QCLs. Kutendeseka kweHamamatsu Photonics KK uye New Energy uye Industrial Technology Development Organisation (NEDO).
Vachishandisa tekinoroji yaHamamatsu iripo microelectromechanical system (MEMS) tekinoroji, ivo vanogadzira vakagadzirisazve QCL's MEMS diffraction grating, ichidzikisa kusvika pa1 / 10th saizi yekugutsikana kwakajairika. Chikwata chakashandisawo magineti madiki akarongedzwa kudzikisira nzvimbo isina basa, uye akanyatso kuunganidza zvimwe zvinhu nemazvo pasi kusvika kumayuniti e01 μm. Izvo QCL zvekunze zviyero zviri 13 × 30 × 13 mm (W × D × H).

Wavelength-yakatsvairwa QCLs inoshandisa MEMS diffraction grating inopararira, inoratidza, uye inoburitsa yepakati-infrared mwenje ichikurumidza kuchinja iyo wavelength. Hamamatsu's wave-yakatsvairwa QCL inogadziriswa muhurefu hwehurefu hwe7 kusvika 8 μm. Range iri rinosvinwa zviri nyore neASO2 uye H2S magasi anoonekwa seanofungidzira kwekutanga kweanogona kuputika kwegomo.

Kuti vakwanise kugadziridza wavelength, ivo vaongorori vakashandisa dhizaini dhizaini tekinoroji iyo inoenderana neyakanyanya kuitika. Kune iyo-inoburitsa mwenje weiyo QCL element, ivo vaishandisa anti-kuyambuka mbiri-yepamusoro-nyika dhizaini.

Kana wavelength-yakatsvairwa QCL ikasanganiswa neyekutyaira sisitimu inogadzirwa neAIST, inogona kuzadzikisa wavelength yekutsvaira kumhanya iyo inowana inoenderera yepakati-infrared mwenje masekondi mukati me20 ms. Iyo QCL yekumhanyisa-mhanya kutora kweiyo spectrum ichaita kuti kuongororwa kwezvinoitika zvenguva pfupi zvinoshanduka nekukurumidza nekufamba kwenguva. Kugadziriswa kweiyo QCL ndeye 15 nm, uye yayo yepamusoro yepamusoro kuburitsa ingangoita 150 mW.

Parizvino, vaongorori vazhinji vakashandisa kuona uye kuyera magasi anoputika munguva chaiyo vane maelektrochemical sensors. Ma electrode mune aya ma sensors - uye mashandiro eanowongorora - anoderera nekukurumidza, nekuda kwekugara uchionekwa nemweya une chepfu. Ese-anowona gasi vaongorori vanoshandisa hurefu-hupenyu mwenje sosi uye vanoda kushoma kugadziriswa, asi iyo yakajeka mwenje sosi inogona kutora yakawanda nzvimbo. Saizi yeaya anoongorora inovaita kuti vaome kuisa padyo nemakoropu anoputika.

Chizvarwa chinotevera-volcanic gasi inoongorora system, yakashongedzerwa neiyo diki wavelength-yakatsvairwa QCL, ichapa volcanologists neese-optical, compact, inotakurika unit ine yakanyanya kunzwisisika uye nyore kugadzirisa. Vatsvagiri veHamamatsu nevamwe vavanoshanda navo kuAIST neNew Energy uye Industrial Technology Development Organisation (NEDO), iyo yakatsigira chirongwa ichi, vacharamba vachiongorora nzira dzekuwedzera kunzwisisika kwemuongorori uye kudzora kugadzirisa.

Chikwata chiri kuronga kuwanda kwemaonero kuti kuyedze uye kuratidza inotakurika analyzer. Zvigadzirwa zvinoshandisa wavelength-yakatsvairwa QCL uye kutyaira maseketi pamwe neHamamatsu photodetectors zvakarongerwa kuburitswa muna 2022.
