Kufurira zvinhu zvehurongwa kukanganisa kwephotodetectors
Kune akawanda ma paramita ane hukama nesystem kukanganisa kwemafotodetectors, uye iwo chaiwo mafungidziro anosiyana zvichienderana neakasiyana mapurojekiti mapurojekiti. Naizvozvo, iyo JIMU Optoelectronic Research Assistant yakagadziridzwa kuti ibatsire optoelectronic vaongorori nekukurumidza kugadzirisa kukanganisa kwehurongwa hwemafotodetectors uye nekukurumidza kuvaka optoelectronic masisitimu, nekudaro kupfupisa kutenderera kweprojekiti uye kudzivirira kutanga kubva pakatanga kuongororwa nekugadzira.
3. Kuramba
(1) Kupikisa kukosha: Kusarudzwa kwemaitiro akakodzera ekupikisa kunobatanidzwa mukuwedzera kwekugadzirisa kwekushanda amplifiers, kuenzanisa kupikisa, RC kusefa, etc. Kupikisa kukosha hakufaniri kunge kwakakura, sezvo hukuru hwekupikisa hunokosha, husina simba hwechiratidzo, hurombo hunopesana nekupindira, uye hukuru hweGaussian white noise. Izvo hazvifanirwe kunge zvidiki zvakanyanya, sezvo simba rekushandisa richiwedzera uye rinogona kuburitsa kupisa uye kukanganisa hupenyu.
(2) Simba: Iva nechokwadi chokuti P = I ^ 2 * R haipfuuri simba rayo rakarongwa, uye kudzivirira kupikisa kubva pakupisa, haifaniri kudarika hafu yesimba rayo.
(3) Kururama: Haina zvazvinoita pakururama kweiyo recalibration system.
(4) Kudonha kwetembiricha: Kudonha kwetembiricha yevanopikisa chinhu chakakosha chekutarisa mukuverenga kwekukanganisa kwakarongeka.
4. Capacitor
(1) Capacitance kukosha: Kune RC mafirita ane chekuita nemasekete, nguva dzenguva, nezvimwewo, kukosha kwekugona kunoda kuverengerwa nemazvo. Iyo sisitimu dhizaini haigone kufuratira nguva yenguva yekumisikidzwa kwemasaini kungosefa kunze kwekukanganisa ma frequency. Izvo zvinodikanwa kuti utarise zvinodikanwa zveese frequency domain uye iyo nguva domain panguva imwe chete kusangana nezvinodiwa zvekusefa uye chiratidzo chekugadzwa nguva.
(2) Kunyatsorongeka: Kana chikumbiro chako chakabatana ne-high-frequency signals kana kuti inoda yepamusoro sefa bandwidth, unoda kusarudza capacitors nepamusoro-soro. Kazhinji, izvo zvinodiwa chaizvo zvema capacitors hazvina kunyanyo nyorova.
(3) Kudonha kwe tembiricha.
(4) Kuramba kudzvinyirira: Inofanirwa kusangana neinodzikisira dhizaini maitiro, neyakajairwa 20% inodzikisira application margin.
4. Kushanda tembiricha
(1) Sarudza tembiricha yekushanda zvichienderana nezvinodiwa zvechigadzirwa zvephotodetector. Semuenzaniso: Kushanda tembiricha yeimwe IVD yekurapaphotodetector chigadzirwairi 10 kusvika 30 ℃. Ichi chinodiwa chetembiricha chakanyanya kukosha nekuti maparamita ane chekuita nekudonha kwetembiricha yezvikamu zvakaita seanoshanda amplifiers, resistors, uye ADCs ambotaurwa zvese zvine chekuita nekushanda kwekushisa kwechigadzirwa. Tichifunga nezve musiyano wetembiricha uye pesvedzero yekusiyana kwetembiricha pasi pemashandisirwo chaiwo emamiriro ekunze, zvinova nechokwadi chekuti huwandu hwakazara hwekuchinja mune imwe neimwe parameter mukati meiyi tembiricha renji haipfuure chinodikanwa chekupedzisira che.photoelectric systemkukanganisa.
(2) Sarudza kana kune zvikamu zvinotarisa humidity-sensitive components uye kana humidity nharaunda zvinodiwa zvinosangana: Sarudza huwandu hwekuchinja kwehunyoro munzvimbo yekushanda uye maparameter ezvishandiso zvinokanganisa humidity zvinokanganisa mhedzisiro.
5. Kugadzikana uye kuvimbika kwegadziriro inoenderana nekugadzirisa kugadzikana kwe photodetector. Chinodiwa pakuita kwakakodzera system kukanganisa kuverenga ndechekuti sisitimu yakagadzikana uye haifanirwe kukanganiswa neEMC-inoenderana nharaunda; zvikasadaro, masvomhu ose haana maturo. Nekuda kwekugumira kwenzvimbo, chitsauko chino hachizotsananguri zvimwe. Zvinhu zviviri zvinotevera zvinofanira kufungwa nezvazvo. Mukugadzirwa kwedunhu, kufunga kwakasimba kwekudzivirira uye nhanho dzekudzivirira dzinofanirwa kutorwa kune EMI neEMS. B. Iyo casing, kudzivirirwa kwetambo dzekubatanidza, nzira dzekugadzirisa pasi, nezvimwewo zvinodawo kuongororwa uye kuongororwa.
