Kutanga uye Kushanduka kweLaser Ranging
Zvichibva pakutanga kwema1960, ma "laser rangefinders" ekutanga akagadzirwa zvakanyanya kuti ashandiswe muhondo [1Mumakore apfuura, tekinoroji iyi yakashanduka uye yakawedzera mukurumbira wayo muzvikamu zvakasiyana-siyana, kusanganisira kuvaka, topography, uye ndege [2], uye zvichipfuura.
Tekinoroji yeLaserinzira yekuyera zvinhu zveindasitiri isingabatanidzwe iyo inopa mabhenefiti akawanda kana tichienzanisa nenzira dzechinyakare dzekutarisa zvinhu:
- Inobvisa kudiwa kwekubata panyama nepamusoro pekuyera, ichidzivirira kukanganisika kunogona kukonzera zvikanganiso zvekuyera.
- Inoderedza kupera kweganda panzvimbo yekuyera sezvo isingasanganisire kubata muviri panguva yekuyera.
- Yakakodzera kushandiswa munzvimbo dzakakosha uko maturusi ekuyera akajairika asingashande.
Nheyo dzeLaser Ranging:
- Kuenzanisa kweLaser kunoshandisa nzira nhatu huru: kusiyanisa kwepulse nelaser, kusiyanisa kwelaser phase, uye kusiyanisa kwelaser triangulation.
- Nzira imwe neimwe inobatanidzwa nematanho chaiwo ekuyera anoshandiswa zvakanyanya uye mazinga ekururama.
01
Kufamba kweLaser Pulse:
Inonyanya kushandiswa pakuyera daro refu, kazhinji kupfuura daro remakiromita, nekunyatsorongeka kwakaderera, kazhinji padanho remita.
02
