I-Laser esukela ubuchwepheshe

Isimiso selaserrangefinder
Ngaphezu kokusetshenziswa kwezimboni kwama-lasers ekucubunguleni izinto ezibonakalayo, eminye imikhakha, efana ne-aerospace, amasosha kanye neminye imikhakha nayo ikhula njalo.izinhlelo laser.Phakathi kwazo, i-laser esetshenziswa ezindizeni nakwezempi iyanda, futhi ukusetshenziswa kwe-laser kulo mkhakha ikakhulukazi i-laser esukela.Isimiso se-laser esukela - ibanga lilingana nezikhathi zesivinini.Isivinini sokukhanya sinqunywa, kanye nesikhathi sokuhamba yokukhanya ingatholwa ngomshini wokubona, futhi ibanga lento ezolinganiswa lingabalwa.
Umdwebo umi kanje:

I-laser divergence factor inethonya elikhulu ekunembeni kwe-laser rangefinder.Iyini i-divergence factor?Isibonelo, umuntu oyedwa uphethe ithoshi kanti omunye uphethe i-laser pointer.Ibanga lokushiswa kwemisebe ye-laser pointer likhulu kunelethoshi, ngoba ukukhanya kwethoshi kuhluke kakhulu, futhi isilinganiso sokuphambuka kokukhanya kubizwa ngokuthi i-divergence factor.Ukukhanya kwe-laseriyafana ngokwethiyori, kodwa uma ibanga lesenzo likude, kuba nokuhlukana kokukhanya.Uma i-Divergence Angle yokukhanya icindezelwe, ukulawula izinga lokuhlukana kwelaser kuyindlela yokuthuthukisa ukunemba kwe-laser rangefinder.

Isicelo selaser rangefinder
I-laser rangefinder isetshenziswa kakhulu emkhathini, i-Apollo 15 enyangeni ngesethi ekhethekile yemishini - i-Angle reflector enkulu, esetshenziselwa ukukhombisa i-laser beam evela eMhlabeni, ngokurekhoda isikhathi sokuya nokubuya ukubala ibanga phakathi koMhlaba nomhlaba. inyanga.
Ngasikhathi sinye, ama-laser rangefinders nawo asetshenziswa kwezinye izindawo ze-aerospace:
1, i-laser rangefinder kuhlelo lwezempi
Eziningi zei-optoelectronicamasistimu okulandelela ezindizeni zokulwa kanye nemishini yaphansi afakwe i-laser rangefinder, ekwazi ngokunembile ibanga lesitha futhi ilungiselele ukuzivikela ngokufanele.
2, ukusetshenziswa kwe-laser esukela ekuphenyweni kwezwe kanye nemephu
I-laser rangefinder ocwaningweni nasekufakweni kwemephu yendawo ngokuvamile ibizwa ngokuthi i-laser altimeter, ephathwa kakhulu endizeni noma isathelayithi ukukala idatha yokuphakama.
3. Ukusetshenziswa kwe-laser esukela kumkhumbi-mkhathi ozimele
Ukusebenzisa ama-probe angenamuntu ukuze kuhlale phezu kwezindikimba zasezulwini okuqondiwe kuzo njengenyanga, i-Mars noma ama-asteroid ukuze kuhlolwe indawo noma ukubuya kwamasampula kuyindlela ebalulekile yomuntu yokuhlola indawo yonke, futhi kungenye yezindawo ezishisayo ekuthuthukisweni. yemisebenzi yokuhlola indawo ejulile esikhathini esizayo.Ukwethula amasathelayithi noma ama-probe endaweni ethambile ebusweni bamanye amaplanethi kuyisiqondiso esibalulekile sokuhlola indawo.
4. Ukusetshenziswa kweukukhanya kwe-laseresikhaleni sokuhlangana okuzimele kanye nokufika
I-Space autonomous rendezvous kanye ne-docking kuyinqubo eyinkimbinkimbi kakhulu nenembayo.
Inqubo ye-Rendezvous ibhekisela ekuhlanganeni kwezindiza ezimbili noma ngaphezulu ku-orbit yasemkhathini ngokwendawo nesikhathi esinqunyiwe, ibanga lesenzo liyi-100km ~ 10m, ukusuka kude ukuya eduze nesidingo sokuqondiswa kwe-GPS, i-microwave radar, i-lidar, i-optical imaging sensor measurement means, isikhala. i-docking ibhekisela ezindizeni ezimbili ezisemkhathini ngemva kokuhlangana esakhiweni somshini sayo yonke.Ibanga lokusebenza liyi-10 ~ 0m, elifezwa ikakhulukazi izinzwa zokuqondisa amavidiyo (AVGS).

5. Ukusetshenziswa kwe-laser esukela emkhakheni wokutholwa kwemfucumfucu yasemkhathini
Ukutholwa kwemfucumfucu emkhathini kungenye yezinkambu ezibalulekile zokusetshenziswa kobuchwepheshe bokuthola i-laser emkhathini.
