I-Laser RangeFinders sebephenduke amathuluzi asemqoka ezinkambeni ezisukela emidlalweni kanye nokwakha ucwaningo lwezempi nolwesayensi. Lawa madivayisi alinganisa amabanga anokunemba okumangazayo ngokukhipha ama-laser pulses futhi ahlaziye ukuboniswa kwawo. Ukuze baqonde ukuthi basebenza kanjani, kubalulekile ukudiliza izakhi zabo eziyisisekelo. Kulesi sihloko, sizohlola izingxenye ezibalulekile ze-Laser RangeFinder kanye nezindima zazo ekuletheni izilinganiso ezinembile.
1. I-Laser Diode (Emitter)
Enhliziyweni yazo zonke izinhlobo ze-Laser RangeFinder yi-Laser Diode, ekhiqiza ugongolo olunobumbano olusetshenziselwe ukukalwa. Imvamisa isebenza kwi-spectrum eseduze ye-infrared (isib., 905 NM noma i-1550 NM wavengths), i-diode ikhipha amafushane, ama-pulses agxile kakhulu. Ukukhetha kwe-Wavelength Baltical Safety (ukuvikela amehlo abantu) kanye nokusebenza ezimweni ezahlukahlukene zezemvelo. Ama-diode asezingeni eliphakeme aqinisekisa ubukhulu be-beam beam, abucayi ngokunemba okude.
2. I-Optical Lens System
Uhlelo lwe-lens lwe-optical lens lusebenzisa imisebenzi emibili yokuqala:
- Ukuhlangana: Ugongolo lwe-laser olukhishwe lunciphisiwe futhi luhambisane nogongolo olufana lokunciphisa ukuhlakazwa ibanga.
- Ukugxila: Ukukhanya okubuyayo okubonisiwe, amalensi agxilisa ama-photons ahlakazekile emshweni.
Ama-Rangefinders athuthukile angafaka ama-lens aguqukayo noma amakhono okusondeza ukujwayela osayizi noma amabanga ahlukahlukene.
3. I-PhotoDETECECECECECECE (Otholayo)
I-PhotoDesetor - imvamisa i-avalanche photodiode (APD) noma i-pin diode-ithumba ama-laser pulses abonisiwe. I-APD ikhethelwe izinhlelo zokusebenza ezinde ezibucayi ngenxa yokuzwela okuphezulu kanye nekhono lokukhulisa amasiginali abuthakathaka. Ukuhlunga ukukhanya okukhona (isib
4. Isikhathi-of-flight (tof) ukujikeleza
I-Time-of-Flight Circuitry yingqondo ebalwa ibanga lebanga. Kukala isikhathi ukubambezeleka phakathi kokushayela okukhishwe kanye nokuboniswa okutholakele. Njengoba ukukhanya kuhamba ngejubane elaziwayo (~ 3 × 10 ⁸ m / s), ibanga libalwa kusetshenziswa ifomula:
Ama-timers we-Ultra-High-speed (izinqumo ezikuPicoseconds) zibalulekile ukunemba kwezinga lama-millimeter, ikakhulukazi kwizicelo ezinamafuphi.
I-5. Iyunithi yokusebenza yesiginali
Idatha eluhlaza evela kwi-PhotoDete icutshungulwa yi-microcontroller noma iprosesa lesiginali yedijithali (DSP). Le yunithi yokuhlunga umsindo, inxephezela ngezinto zemvelo (isib. I-Attenuation Atmospheric), futhi iguqula izilinganiso zesikhathi ekufundeni ibanga. Ama-algorithms athuthukile nawo angaphatha ama-echoes amaningi (isib. Ukunganaki amahlamvu lapho kubhekiswa isiqu somuthi).
6. Isibonisi esibonakalayo kanye nomsebenzisi
Iningi le-Rangenifinders libonisa isibonisi se-LCD noma i-OLED ukukhombisa izilinganiso, kaningi ngezindlela ezithandwayo ezifana nokulungiswa komthambeka, ukuskena okuqhubekayo, noma ukuxhumana kwe-Bluetooth kokugawulwa kwedatha. Ukufakwa komsebenzisi-izinkinobho, izinkinobho zokuthinta, noma ukudayela okujikelezayo - Vumela ngokwezifiso amacala athile okusetshenziswa, njengegalofu, ukuzingela, noma ukucwaninga.
7. Ukunikezwa kwamandla
Ibhethri elishajekayo elihlangene (isib. I-Li-Ion) noma amaseli achithwa amandla idivaysi. Ukusebenza kahle kwamandla kubalulekile, ikakhulukazi amamodeli aphathwayo asetshenziswe kuzilungiselelo zangaphandle. Abanye ama-rangefinders afaka izindlela zokonga amandla ukwelula impilo yebhethri ngesikhathi sokungasebenzi.
8. Izinhlelo zokugcina kanye nezinhlelo zokukhwela
Izindlu zenzelwe ukuqina kanye ne-ergonomics, zivame ukuhlanganisa izinto ezingamelana namanzi noma ezishaqisayo (izilinganiso ze-IP). Ukuhlanganiswa neminye imishini (isib
Konke kusebenza kanjani ndawonye
1. I-Laser Diode ikhipha ukushaya kwelitshe libheke kwelitshe.
2. Uhlelo lokubona luqondisa ugongolo futhi luqoqe ukukhombisa.
3. I-PhotoDETECT ithumba isinali yokubuyisa, ehlungwe ku-ambient umsindo.
4. I-tof circuitry ibala isikhathi esidlulile.
I-5. Iprosesa iguqula isikhathi ibanga futhi ikhombise umphumela.
Ukugcina
Ukusuka ekuqondeni kwe-Laser Diode yayo ekwakhiweni kwama-algorithms akwa-algorithms ayo, ingxenye ngayinye ye-Ranger RangeFinder idlala indima ebalulekile ekuqinisekiseni ukunemba nokwethembeka. Noma ngabe uyi-golfer ukwahlulela i-Putt noma i-Engineer Mapping Terrain, ukuqonda lezi zinto kusiza ekukhetheni ithuluzi elilungile lezidingo zakho.
