Uburyo Laser Ranging ikora

Ukurikije ihame shingiro, hari ubwoko bubiri bwuburyo bwa laser: igihe-cyo guhaguruka (TOF) kuringaniza nigihe kitari-cyo guhaguruka. Hariholazerina fase-ishingiye kuri laser iringaniza mugihe-cyo guhaguruka.

Impanuka zingana nuburyo bwo gupima bwakoreshejwe bwa mbere mubushakashatsi no gushushanya hakoreshejwe ikoranabuhanga rya laser. Kuberako impande zinyuranye za laser ari nto, igihe cya laser pulse igihe ni gito cyane, kandi imbaraga zako kanya nini cyane, kuburyo ishobora kugera kure cyane. Muri rusange, intego ya koperative ntabwo ikoreshwa, ariko ikwirakwizwa ryerekana ibimenyetso byumucyo nintego yapimwe ikoreshwa mugupima intera.

Ihame ryuburyo bwa pulsed ranging bwumvikana neza. Isaha-yumurongo mwinshi itwara compte kugirango ibare igihe kiri hagati yo kohereza no kwakira impiswi, ibyo bigatuma igihe cyisaha yo kubara ari gito cyane ugereranije nigihe cyo kohereza no kwakira impiswi kugirango hamenyekane neza neza, ubwo buryo bwo gutandukanya burakwiriye- gupima intera.

Inguni yohereza imyuka ya lazeri ni nto, ingufu ziba zegeranye mu kirere, kandi imbaraga ako kanya ni nini. Ukoresheje ibyo biranga, bitandukanye kandi birebirelasers, lidar, nibindi birashobora gukorwa. Kugeza ubu, impanuka ya laser ikoreshwa cyane mugupima imiterere ya topografiya na geomorphologi, ubushakashatsi bwa geologiya, gupima ubwubatsi, gupima uburebure bwindege, kwirinda inzitizi n’ibikoresho,gupima intera y'ingandanibindi bikoresho bya tekiniki.

Icyiciro cya laserni ugukoresha inshuro ya radio bande kugirango uhindure amplitude yumurambararo wa laser hanyuma upime ubukererwe bwicyiciro cyatewe numucyo wo guhinduranya ugenda usubira kumurongo wo gupima, hanyuma uhindure intera ihagarariwe nubukererwe bwicyiciro ukurikije uburebure bwumuraba y'urumuri rwahinduwe. Nukuvuga ko igihe gisabwa kugirango urumuri rugende inyuma unyuze kumurongo wubushakashatsi upimwa nuburyo butaziguye. Icyiciro cya laser gisanzwe gikoreshwa murwego rwo kugereranya neza. Bitewe nukuri kwinshi, mubisanzwe murutonde rwa milimetero, kugirango ugaragaze neza ibimenyetso kandi ugabanye intego yapimwe kumwanya runaka uhuye neza nukuri kwiki gikoresho, iki gikoresho cyagutse gifite ibikoresho byerekana icyerekezo cyitwa koperative. isahani.

Icyiciro cya laser gisanzwe gikwiranye no gupima intera ngufi na hagati, kandi ibipimo byo gupima bishobora kugera kuri milimetero. Nuburyo nuburyo bufite uburebure buri hejuru kuri ubu. Icyiciro kiringaniye ni uguhindura ubukana bwurumuri rwumucyo wasohotse hamwe nikimenyetso cyahinduwe, kandi ugapima mugihe utaziguye mugupima itandukaniro ryicyiciro, ibyo bikaba bitoroshye cyane kuruta gupima igihe cyurugendo-rugendo.

Niba ushaka kumenya amakuru yubuhanga hamwe nibicuruzwa bijyanye na laser range, nyamuneka twandikire.
