Nyorera kune yedu Social Media for Prompt Post
Nguva yakananga-ye-kubhururuka Iyi tekinoroji ndeyekuita kwakasiyana-siyana kwekushandisa, kubva pakunzwa kushushikana mumutengi emagetsi emagetsi kune addar masisitimu mune zvemotokari zvinoshandiswa. Pazasi pamushonga wayo, maDtof masisitimu ane zvikamu zvinoverengeka zvakakosha, mumwe nemumwe achitamba basa rakakosha mukuita seyakaenzana kureba kuyerwa.
Iyo core zvikamu zveDtof Systems
Laser mutyairi uye laser
Iyo Laser Driver, chikamu chePivotal cheTransmitter Circuit, Gadzira Dhijitari Pulse Zviratidzo kudzora iyo LASE's Humission kuburikidza neMosFet vachishandisa. Lasers, kunyanyaVertical Cavity Specus inobvisa lasers. Zvichienderana nekunyorera, wavelength ye 850nm kana 940nm inosarudzwa kuyera pakati pe solar spectrum toporption peaks uye sensor Quantum inoshanda.
Kuendesa uye kugamuchira optics
Padivi rekupararira, rakapfava renji renji kana musanganiswa wekusanganisa kwezvinhu uye zvinoshamisa zvinhu zvinhu (zvinoita) zvinoregedza laser beas kuyambuka munda waunoda. Iyo inogamuchira optics, inovanzika pakuunganidza mwenje mukati mechinangwa chevanoona, batsirwa kubva kuLenses neChilumination F-nhamba yekuvhenekera
Spad uye Sipm Sensors
Imwe-Photon Avalanche Diodes (SPad) uye Silicon Photomultiplielers (Sipm) ndiyo yekutanga sensors mune dtof masystem. Spads inosiyaniswa nekugona kwavo kupindura kune imwe mifananidzo, inokonzeresa nzvimbo yakasimba yaAvanche iripo neiyo photon imwe chete, ichiita kuti ive yakakodzera zviyero zvakakwirira. Nekudaro, saizi yavo yakakura ye pixel ichienzaniswa neyechinyakare cms sensors inogumira spatial resolution yeDtof masystem.
Nguva-to-digital shandura (TDC)
Dunhu reTDC rinotsanangura analog masaini mumagazini emadhijitari anomiririrwa nenguva, tora nguva chaiyo yekunyora yega yega phonse yakanyorwa. Uku kurongeka kwakakosha kwekusarudza chinzvimbo chechinhu chakanangwa zvichienderana neHistogram yeakarekodwa purses.
Kuongorora Dtof Performance Parameter
Kuongororwa huwandu uye chokwadi
Kuonekwa kwakadaro kweiyo dtof system yedhireti inowedzera kusvika pakusvika kwayo yemwenje inopenya inogona kufamba uye kuratidzwa kudzoserwa kune sensor, inozivikanwa chaizvo kubva paruzha. Zvekutenga zvemagetsi, iyo inowanzoitika mukati me5m renji, uchishandisa vcsels, nepo mafambiro ekushandisa emagetsi angangoda kuwanikwa kwezororo re100m kana kupfuurafiber lasers.
Dzvanya apa kuti udzidze zvimwe nezve chigadzirwa
Maximum isingadzivisike huwandu
Iyo yakakwira huwandu pasina ambiguity zvinoenderana nekupindirana pakati pebiting pulsed uye modulation frequency ye laser. Semuenzaniso, ne modulation frequency ye 1mhz, iyo isingaoneki huwandu inogona kusvika kusvika 150m.
Chaiyo uye kukanganisa
Precision muDtof Systems yakaganhurwa nePulse Yakapamhama neHurumende, apo zvikanganiso zvinogona kusarudzika kubva kune zvakasiyana-siyana mutyairi, kusanganisira sensor sensor, uye tdc hupfumi hwechinzvimbo. Nzira dzinoshanda senzira yekunongedzera spad inogona kubatsira kudzikisira izvi zvikanganiso nekumisa bhasikoro rekuita nguva uye chinhambwe.
Ruzha uye kukanganisa kuramba
Sistir Systems inofanirwa kurwisa neruzha rwemashure, kunyanya munzvimbo dzakasimba dzechiedza. Nhungamiro dzakadai sekushandisa akawanda spad pixels ane akasiyana etivation mazinga anogona kubatsira kubata dambudziko iri. Pamusoro pezvo, kugona kwaDtof kusiyanisa pakati pezvizhinji uye multipathi zvinoratidzira zvinokwidziridza zvakasimba pakupindira.
Spatial resolution uye kushandiswa kwemagetsi
Kufambira mberi mu spad sensor tekinoroji, sekushandurwa kubva kumberi kwekutanga-parutivi (FSI) yekuzvivharira (BSI) maitiro, kuve nekuvandudza zvakanyanya Photon extorption uye sensor yekubudirira. Kufambira mberi uku, kwakabatanidzwa nechimiro chakasvibirira cheDtof masisitimu, zvinoguma nekudzikira masimba emasimba zvichienzaniswa nekuenderera mberi kwemasisitimu akawanda senge.
Ramangwana reDtof tekinoroji
Pasinei nezvinopesana nedzvinyiriro uye mutengo wakabatana neDtof tekinoroji, zvakanakira chaizvo, zvakaringana, uye kushanda nesimba kunoita kuti imhombwe inosimudzira yezvirangaridzo muminda dzakasiyana siyana muminda dzakasiyana siyana. Semunhu tekinoroji tekinoroji uye danho remagetsi ramba riripo kuti rirambe riripo, masisitimu emadhorobha akagadzirira kurerwa kwakawanda, achityaira mune zvemagetsi zvemagetsi zvemagetsi, kuchengetedzeka kwemotokari, uye kupfuura.
