HAMAMATSU, Japane, Phato 25, 2021 - Hamamatsu Photonics le Setsi sa Naha sa Saense e Tsoetseng Pele ea Liindasteri le Theknoloji (AIST) Tokyo ba sebelisane 'moho le sistimi e tsamaisang mahlo ea khase bakeng sa ho bolela esale pele ho phatloha ha seretse se chesang ka kutloisiso e phahameng. Ntle le ho fana ka tlhahlobo e tsitsitseng, ea nako e telele ea likhase tse foqohang seretse se chesang haufi le liphula tsa seretse se chesang, mohlahlobi ea nkehang habonolo a ka sebelisoa ho fumana ho tsoa hoa khase e chefo limeleng tsa likhemik'hale le likhoerekhoere le litekanyo tsa sepakapaka.

Sistimi ena e na le miniaturized, wavelength-swept quantum cascade laser (QCL) e ntlafalitsoeng ke Hamamatsu. Hoo e ka bang 1 / 150th boholo ba li-QCL tse fetileng, laser ke QCL e nyane ka ho fetesisa lefatšeng ka bophara. Sistimi ea ho khanna ea sistimi ea ho lekola khase, e ntlafalitsoeng ke AIST, e tla lumella QCL e nyane hore e kenngoe ho lihlahlobi tse bobebe, tse nkehang habonolo tse ka tsamaisoang kae kapa kae.
QCL e nyane ka ho fetesisa lefatšeng ke 1 / 150th feela ka boholo ba li-QCL tse fetileng tsa wavelength. Ka tumello ea Hamamatsu Photonics KK le New Energy and Industrial Technology Development Organisation (NEDO).
Ha ba sebelisa theknoloji e seng e ntse e le teng ea Microelectromechanical (MEMS) ea Hamamatsu, bahlahisi ba ile ba hlophisa bocha grating ea QCL ea MEMS, ba e fokotsa ho fihlela 1 / 10th boholo ba likhaello tse tloaelehileng. Sehlopha se boetse se sebelisitse makenete e nyane e neng e hlophiselitsoe ho fokotsa sebaka se sa hlokahaleng, mme ka nepo e bokella likarolo tse ling ka nepo ho fihlela li-unit tsa 0.1 μm. Litekanyo tsa kantle tsa QCL ke 13 × 30 × 13 mm (W × D × H).

Li-QCL tse fieloang ke Wavelength li sebelisa grating ea MEMS e qhalakaneng, e bonts'a, le ho fana ka leseli le bohareng ba infrared ha e ntse e suthisa bokahohle kapele. QCL ea Hamamatsu e fietsoeng ka leqhubu e ka khonahala bokaholong ba bokahohle ba 7 ho isa ho 8 μm. Mokoloko ona o monngoa habonolo ke likhase tsa SO2 le H2S tse nkoang e le tse ka bolelang esale pele hore ho ka ba le ho foqoha ha seretse se chesang.

Ho fihlela bokahohle bo lokisehang, bafuputsi ba sebelisitse theknoloji ea moralo oa lisebelisoa e ipapisitseng le phello ea bongata. Bakeng sa lera le hlahisang leseli la karolo ea QCL, ba sebelisitse moralo o khahlano le ho tšela o habeli-o phahameng.

Ha bokahare ba bokahare ba QCL bo kopantsoe le sistimi ea drive e ntlafalitsoeng ke AIST, e ka fihlela lebelo le fihlang la waveleng le fumanang khanya e sa khaotseng ea infrared light ka hare ho 20 ms. Phallo e potlakileng ea QCL ea ponahalo e tla tsamaisa litlhahlobo tsa liketsahalo tsa nakoana tse fetohang ka potlako ha nako e ntse e tsamaea. Qeto ea QCL ea ponahalo e ka ba 15 nm, 'me palo ea eona e phahameng ea tlhoro e ka ba 150 mW.

Hajoale, bahlahlobi ba bangata ba neng ba tloaetse ho lemoha le ho lekanya likhase tsa seretse se chesang ka nako ea 'nete ba na le li-sensor tsa motlakase. Li-electrode tse hlahlobang tsena - le ts'ebetso ea sehlahlo - li senyeha kapele, ka lebaka la ho pepesehela khase e chefo khafetsa. Bahlahlobi bohle ba khase ba sebelisa mohloli oa khanya ea bophelo bo bolelele mme ba hloka tlhokomelo e nyane, empa mohloli oa leseli la optical o ka nka sebaka se ngata. Boholo ba lihlahlobisisi tsena bo etsa hore ho be thata ho li kenya pela li-crater tsa volcano.

Sistimi e latelang ea moloko o tlang oa ho lekola ha seretse se chesang, e nang le QCL e nyane ea bokaholimo, e tla fa litsebi tsa seretse se chesang sesebelisoa se nang le Optical, compact, portable e nang le kutloisiso e phahameng le tlhokomelo e bonolo. Bafuputsi ba Hamamatsu le basebetsi-'moho le bona ho AIST le New Energy and Industrial Technology Development Organisation (NEDO), ba tšehetsang projeke, ba tla tsoelapele ho batlisisa mekhoa ea ho eketsa kutloisiso ea mohlahlobi le ho fokotsa tlhokomelo.

Sehlopha se rera ho shebella mefuta e mengata ho leka le ho bonts'a mohlahlobi ea nkehang. Lihlahisoa tse sebelisang QCL ea bokahohle le ho tsamaisa lipotoloho hammoho le li-photodetectors tsa Hamamatsu li reretsoe ho lokolloa ka 2022.
