Kare muna 1916, nyanzvi yefizikisi yechiJudha yakakurumbira Einstein akawana chakavanzika chemalaser. Laser (zita rakazara: Light Amplification by Stimulated Emission of Radiation), zvichireva kuti "amplification by stimulated radiation of light", inorumbidzwa seimwe nzira huru yakaitwa nevanhu kubvira muzana remakore rechi20, ichitevera simba renyukireya, makomputa, uye semiconductors. Ndiyo "banga rinokurumidza", "mutongi akarurama kwazvo", uye "chiedza chakanyanya kupenya". Zita rakazara rechiRungu relaser ratove richitaura zvizere maitiro makuru ekugadzira laser. Laser ine mashandisirwo akasiyana-siyana, akadai se laser marking, laser welding, laser cutting, fiber optic communication, laser ranging, LiDAR, nezvimwewo. Nhasi tichataura nezvekuti lasers dzinowana sei basa rekuyera daro.
Nheyo ye laser ranging
Kazhinji, kune nzira mbiri dzekuyera daro uchishandisa ma laser: nzira yekurova uye nzira yechikamu. Nheyo yekurasira kwekurova kwemoyo ne laser ndeyekuti laser inoburitswa nechinhu chinoburitsa chiedza inoonekwa nechinhu chakayerwa uye yobva yagamuchirwa neanogamuchira. Nekunyora panguva imwe chete nguva yerwendo rwekudzokera nekudzoka rwe laser, hafu yemhedzisiro yekumhanya kwechiedza nenguva yekudzoka ndiyo daro riri pakati pechishandiso chinotora chiedza nechinhu chakayerwa. Kururama kwenzira yekurova kwemoyo yekuyera daro kunowanzova +/- 10 centimeters. Nzira yechikamu haiyere chikamu che laser, asi inoyera chikamu chechiratidzo chakagadziriswa pa laser.
Nzira yekusarudza laser
Mushure mekunzwisisa musimboti wekushandiswa kwe laser ranging, ngatitarisei mashandiro chaiwo e laser ranging. Kazhinji, laser ranging chaiyo inoda kushandiswa kwe total reflection prism, nepo rangefinder inoshandiswa pakuyera imba inogona kuyera zvakananga reflection kubva pamusoro pemadziro akatsetseka. Izvi zvinonyanya kuitika nekuti daro racho riri pedyo, uye simba rechiratidzo rinoratidzwa kumashure nechiedza rakasimba zvakakwana. Zvisinei, kana daro racho riri kure zvakanyanya, laser emission angle inofanira kunge yakatarisana ne total reflection mirror, zvikasadaro return signal ichave isina simba rekuwana daro rakarurama. Zvisinei, mu practical engineering, vashandi vanoshandisa laser ranging vanoshandisa mapurasitiki matete senzvimbo dzinoratidza kuti zvinhu zvinogadzirisa dambudziko re severe laser diffuse reflection. Muchina we laser ranging wemhando yepamusoro unogona kuwana kuyera kwakarurama kweanosvika 1 millimeter, zvichiita kuti lasers dzikwane kune dzakasiyana-siyana high-precision measurements.
Sekambani yepamusoro-soro inobatanidza kutsvagisa nekusimudzira nekugadzira, Lumisopot yakagadzira yakazvimirira mamodule e905nm 1200m semiconductor laser ranging, mamodule e1535nm 3-15km erbium glass laser ranging, uye mamwe mamodule ekuyera laser akareba daro refu. Kusiyana nezvimwe zvigadzirwa zvemakambani zve laser ranging, zvigadzirwa zvedu zvinoratidza zvizere hunhu hwehukuru hudiki, huremu hwakareruka, kushanda zvakanaka kwemutengo, uye kugona kupa zvakawanda. Uyezve, mamodheru edu ezvigadzirwa akasiyana-siyana uye anogona kusangana nezvinodiwa zvese zve laser ranging. Kana uchifarira zvigadzirwa zvedu, ndapota inzwa wakasununguka kutibata.
