Yisiphi isibhamu esisetshenziswa yibutho?

Ama-rangefinder e-laser ayizinto ezithuthukisiwe ezenzelwe ukulinganisa ngokunembile amabanga phakathi kwamaphuzu amabili. Lawa madivayisi ngokuvamile athembele kwenye yezindlela ezimbili eziyinhloko: indlela eqondile yesikhathi sokundiza noma indlela yokushintsha isigaba. ama-binoculars e-rangefinder' ikhono lokunikeza izilinganiso zebanga ezinembile liguqule imikhakha ehlukahlukene, ikakhulukazi imisebenzi yezempi.

Intuthuko Yomlando

I-rangefinder yokuqala ye-laser yezikhali, ehlonyiswe nge-ruby laser, yaqala ukusebenza e-US Army's Pitman-Dunn Laboratory eFrankfort Arsenal, ePennsylvania. Iqanjwe ngokuthi i-XM23, le rangefinder yabeka isisekelo sochungechunge lwamadivayisi ayezosetshenziswa kabanzi kuzo zonke izinhlelo zokusebenza zempi. Kuze kube yilapho kufika uchungechunge lwamathangi e-M1 Abrams ngo-1978, i-ruby laser rangefinder yayiyisici esijwayelekile kuzo zonke amathangi empi ayinhloko asetshenziswa yi-US Army. Ukushintshela ku-Nd:YAG laser kamuva kwaletha ukuthuthuka okukhulu ngesivinini kanye nokusebenza kahle, okwaholela ekuhlanganisweni kwayo namathangi e-M1 Abrams namamodeli esikhathi esizayo.

Izinzuzo kanye Nentuthuko Yezobuchwepheshe

Ukunemba kanye nesisombululo

Enye yezinzuzo eziyinhloko zokusebenzisa ubuchwepheshe be-laser ekulinganisweni kwebanga ukuthi ubude be-wavelength obufushane bokukhanya kwe-laser buqhathaniswa nezindlela ze-ultrasonic noma ze-radar. Lesi sici sivumela ukukhanya okugxile kakhulu, okuholela ekuxazululweni kwendawo okuphezulu. Ama-rangefinder ebanga lempi, angalinganisa amabanga ukusuka kumakhilomitha ambalwa kuya kwamashumi, asebenzisa ama-laser pulse anamandla aphezulu. Naphezu kwezinyathelo zokuphepha, la ma-pulse angabangela izingozi emehlweni abantu, okugcizelela ukubaluleka kokusebenza ngokucophelela.

Ukuhlukahluka Kwemithombo Ye-Laser

Ukuthuthuka kwe-laser rangefinders kubone ukusetshenziswa kwemithombo ehlukahlukene ye-laser, okuhlanganisa i-solid-state, i-semiconductor diode, i-fiber, kanye ne-CO2 lasers. Lokhu kuhlukahluka kuqinisekisa ukuthi izinhlelo zokusebenza zempi zingazuza kubuchwepheshe obufanele kakhulu, kucatshangelwa izici ezifana nobubanzi, ukunemba, kanye nezimo zemvelo.

Izicelo Zezempi Zanamuhla

Abaklami Bethagethi Ye-Laser

Abaklami bezinhloso ze-laser sebebaluleke kakhulu empini yanamuhla, benikeza ukunemba okubalulekile ekukhetheni izinhloso zezibhamu. Amandla okufaka ikhodi yama-laser pulses ukuze kube nokunemba okukhulu kuqinisekisa ukuthi ama-projectile ahlala emzileni, kunciphisa iwindi lokuthola futhi kunciphise isikhathi sokusabela kwento eqondiwe. Le nzuzo yamasu ibalulekile ezimweni zempi zanamuhla, lapho isivinini nokunemba kunganquma impumelelo yomsebenzi.

Ukusetshenziswa Okubanzi Nokuhlanganiswa

Namuhla, ama-laser rangefinder abalulekile emabuthweni okuvikela emhlabeni jikelele, anikeza imisebenzi edlula nje ukulinganisa ibanga ukuze ihlanganise nokutholakala kwesivinini esiqondiwe. Njengoba amabanga aphakathi kwamakhilomitha amabili kuya kwangu-25, la madivayisi angasebenza ngokuzimela noma afakwe ezimotweni nasezinkundleni zezikhali. Ukuhlanganiswa nobuchwepheshe bokubona emini nasebusuku kuthuthukisa ukusebenza kwawo, okwenza abe ithuluzi eliguquguqukayo emisebenzini yezempi.

Isiphetho

Ama-rangefinder e-laser ahambe ibanga elide kusukela ekuthuthukisweni kwawo kokuqala aze abe yinto ebalulekile empini yanamuhla. Ukunemba kwawo, okuthuthukiswe yintuthuko yezobuchwepheshe, kudlala indima ebalulekile empumelelweni yemisebenzi yezempi. Njengoba ubuchwepheshe buqhubeka nokukhula, ukusetshenziswa okungenzeka kanye namakhono ama-rangefinder e-laser nakanjani kuzokhula, okunikeza izinzuzo ezinkulu nakakhulu kokubili ezimweni zempi kanye nezomphakathi.
