Imikhiqizo

I-1064nm Wavelength Nanosecond Pulse Fiber Laser iyithuluzi eliklanywe ngokunemba elifanele izinhlelo ze-LiDAR kanye nezinhlelo zokusebenza ze-OTDR. Iqukethe ububanzi bamandla aphezulu obulawulwayo kusukela ku-0 kuya ku-100 watts, okuqinisekisa ukuzivumelanisa nezimo kuzo zonke izimo zokusebenza. Izinga lokuphindaphinda elilungisekayo le-laser lithuthukisa ukufaneleka kwayo ekutholakaleni kwe-Time-of-Flight LIDAR, okukhuthaza kokubili ukunemba nokusebenza kahle emisebenzini ekhethekile. Ngaphezu kwalokho, ukusetshenziswa kwayo kwamandla aphansi kugcizelela ukuzibophezela komkhiqizo ekusebenzeni okungabizi kakhulu nokuqaphela imvelo. Lokhu kuhlanganiswa kokulawula amandla okunembile, izinga lokuphindaphinda eliguquguqukayo, kanye nokusebenza kahle kwamandla kwenza kube yimpahla ebalulekile ezindaweni zobungcweti ezidinga ukusebenza okuphezulu kokukhanya.

LAma-diode e-aser, avame ukufushaniswa ngokuthi i-LD, abonakala ngokusebenza kahle okuphezulu, usayizi omncane kanye nokuphila isikhathi eside. Njengoba i-LD ingakhiqiza ukukhanya okunezakhiwo ezifanayo njengobude besikhathi kanye nesigaba, ukuhambisana okuphezulu kuyisici sayo esibaluleke kakhulu. Amapharamitha obuchwepheshe ayinhloko: ubude besikhathi, i-lth, i-operating current, i-operating voltage, amandla okukhipha ukukhanya, i-divergence angle, njll.

Ama-rangefinder e-laser asebenza ngezimiso ezimbili ezibalulekile: indlela yesikhathi sokundiza ngqo kanye nendlela yokushintsha kwesigaba. Indlela yesikhathi sokundiza ngqo ihilela ukukhipha i-laser pulse ibheke endaweni eqondiwe kanye nokukala isikhathi esithathayo ukuze ukukhanya okubonakalayo kubuye. Le ndlela eqondile inikeza izilinganiso zebanga ezinembile, kanye nesisombululo sendawo esithonywa yizici ezifana nobude be-pulse kanye nesivinini sokuthola.

Ngakolunye uhlangothi, indlela yokushintsha isigaba isebenzisa ukuguqulwa kwe-sinusoidal intensity okunemvamisa ephezulu, okunikeza indlela yokulinganisa ehlukile. Nakuba iletha ukungaqondakali kokulinganisa, le ndlela ithandwa kakhulu kuma-rangefinders aphathwayo ukuze amabanga aphakathi.

Lawa ma-rangefinder anezici ezithuthukisiwe, okuhlanganisa namadivayisi okubuka okukhulisa okuguquguqukayo kanye nekhono lokukala ijubane elihlobene. Amanye amamodeli enza ngisho nokubala indawo kanye nevolumu futhi enze lula ukugcinwa nokudluliselwa kwedatha, okuthuthukisa ukuguquguquka kwawo.

1. Imodyuli Yokukhanya: Kufaka phakathi umthombo wokukhanya ohleliwe womugqa owodwa nomugqa omningi, kanye nezinhlelo ze-laser zokukhanyisa. Isebenzisa umbono womshini wokwenza izinto ngokuzenzakalela kwasefekthri, ilingisa umbono womuntu wemisebenzi efana nokuqaphela, ukuthola, ukulinganisa, kanye nesiqondiso.


2. Uhlelo: Izixazululo eziphelele ezinikeza imisebenzi eyahlukahlukene yokusetshenziswa kwezimboni, ezisebenza kahle kakhulu futhi zisebenza kahle kakhulu kunokuhlolwa kwabantu, zinikeza idatha elinganiswayo yemisebenzi ehlanganisa ukuhlonza, ukuthola, ukulinganisa, kanye nesiqondiso.
