Intangiriro, Ubwoko bwa Photon Kubara Linear Avalanche Photodetector

Intangiriro, ubwoko bwa photonUmurongo Avalanche Photodetetector

Ikoranabuhanga ryo kubara rya Photon rirashobora kuzuza ibimenyetso bya photon kugirango dutsinde urusaku rwa elegitoroniki ibikoresho bya elegitoroniki biranga amashanyarazi, no kubara amakuru akomeye ya Strictor, kandi tubara amakuru akomeye ya Strictor akurikije agaciro ka metero ya fotoki. Kugirango tumenye kumenya urumuri rukabije, ubwoko bwinshi bwibikoresho hamwe nubushobozi bwa photon bwizwe mu bihugu bitandukanye. Leta ikomeye Avalanche Photodiode (APD Photodetetector) nigikoresho gikoresha fototeri yimbere yimbere yikuramo ibimenyetso byumucyo. Compared with vacuum devices, solid-state devices have obvious advantages in response speed, dark count, power consumption, volume and magnetic field sensitivity, etc. Scientists have carried out research based on solid-state APD photon counting imaging technology.

Igikoresho cya APD PhotodetectorIfite uburyo bwa geiger (gm) hamwe numurongo (LM) uburyo bubiri bwo gukora, ubu buryo bwo kubara tekinike ikoresha ahanini ikoresha cyane cyane ibikoresho bya Geiger. Ibikoresho bya Geiger ibikoresho bifite ubushishozi bukabije kurwego rwa FOTON wenyine hamwe numuvuduko mwinshi wa NanoseConds kugirango ubone igihe kinini. Ariko, uburyo bwa geiger apd bufite ibibazo bimwe na bimwe igihe cyo kumenya, gutahura mu buryo buke bwo gutahura, bityo biragoye kunoza kwivuguruza hagati yikigereranyo cyo gutahura hejuru nubutaka buke. Ifishi ya Photon ishingiye ku hafi-urusaku ku nyubako nyinshi za HGCDTE APD ikorera muburyo bumwe, nta ntera yo gusubiza inyuma, kandi ifite ubwigenge. Ifungura ikibuga gishya cya photon kubara amashusho, nicyerekezo cyingenzi cyiterambere cyibikoresho bibara photon kubara, kandi bifite ibitekerezo byubusa mubyifuzo byubushakashatsi, gutumanaho byubusa, Gukurikirana Ibitekerezo kandi bikurikirana nibindi.

Ihame rya Photon ribara ibikoresho bya HGCDTE APD

Ibikoresho bya APD Photodes bishingiye kubikoresho bya HGCDTE birashobora gutwikira uburebure butandukanye, hamwe na coefficisiteri ya electron na mwobo biratandukanye cyane (reba Ishusho 1 (a)). Bagaragaza uburyo bumwe bwo kuzuye kuranga abatwara mu burebure bwa cream ya 1.3 ~ 11 μM. Nta rusaku rurenze (ugereranije n'urusaku rurenze FSI ~ 2-3 ku bikoresho bya SI APD na FI ~ 4 (B) ku buryo bwo kwiyongeraAvalanche Photodetetector.

Igishushanyo 1 (a) umubano hagati yingaruka za ionisation igipimo cya coodie ya mercury cadmium ivuza ibikoresho nibigize X ya CD; (b) Kugereranya urusaku rurenze f of ibikoresho bya APD hamwe na sisitemu zitandukanye

Ikoranabuhanga ryo kubara rya Photon ni tekinoroji nshya ishobora gukuramo ibimenyetso bya Optique kuva mu rusaku rwubushyuhe mugukemura ikibazo cya Photofectron yakozwe na aPhotodetetectorNyuma yo kwakira fototon imwe. Kubera ko ikimenyetso cyoroheje-urumuri rutatatanye mugihe cyigihe, amashanyarazi arasohoka na detector nabyo ni ibisanzwe kandi bikomeye. Dukurikije ibi biranga urumuri rudakomeye, kwangiza, guhagarika ubuhanga no kubara digitale mubisanzwe bikoreshwa mugutahura urumuri rukomeye cyane. Ikoranabuhanga rya Photon rigezweho rifite ibyiza byinshi, nkibipimo byinshi-kuri-urusaku, ivangura ryinshi, ibipimo byiza byo kurwanya isesengura no gutunganya, ritagereranywa nuburyo ubundi buryo bwo kumenya. Kugeza ubu, sisitemu yo kubara iphone yakoreshejwe cyane mu rwego rwo gupima inganda no gutahura neza, nk'ibyamamare bidahwitse, ibinyabuzima byaho, n'ibindi, bifitanye isano no kugura no kumenya ibimenyetso bidakomeye. Umujinya wa Mercury Cadmium ubwira pofotodetector nta rusaku rurenze, kuko inyungu ziyongera, kandi nta kigereranyo cy'ikimenyetso na nyuma cyo gushyira mu bikorwa ibikoresho bya Photon.
