Sezvo tekinoroji yelaser iri kuramba ichipararira munzvimbo dzakadai sekutarisa, kutaurirana, kufamba, uye kuona kure, nzira dzekushandura nekunyora masaini elaser dzave dzakasiyana-siyana uye dzakaoma. Kuti vawedzere kugona kwekudzivirira kukanganiswa, kunyatsoenderana, uye kushanda zvakanaka kwekutumira data, mainjiniya vakagadzira nzira dzakasiyana-siyana dzekunyora, dzinosanganisira Precision Repetition Frequency (PRF) Code, Variable Pulse Interval Code, uye Pulse Code Modulation (PCM).
Chinyorwa chino chinopa ongororo yakadzama yemhando idzi dzemaencoding elaser kuti ikubatsire kunzwisisa misimboti yadzo yekushanda, maficha ehunyanzvi, uye mamiriro ekushandisa.
1. Kodhi yeKudzokorora Kwakakwana Kwakarurama (Kodhi yePRF)
①Nheyo yeUnyanzvi
Kodhi yePRF inzira yekunyora masaini epulse pafrequency yakatarwa yekudzokorora (semuenzaniso, 10 kHz, 20 kHz). Mumasystem ekuranganisa laser, pulse yega yega inodzoserwa inosiyaniswa zvichienderana nehuwandu hwayo hwe emission frequency, iyo inodzorwa zvakanyanya nesystem.
②Zvinhu Zvikuru
Chimiro chiri nyore uye mutengo wakaderera wekushandisa
Yakakodzera kuyerwa kwenguva pfupi uye zvinangwa zvekutarisa zvakanyanya
Zviri nyore kuwiriranisa nehurongwa hwechinyakare hwewachi yemagetsi
Hazvishande zvakanaka munzvimbo dzakaoma kana munzvimbo dzine vanhu vakawanda nekuda kwenjodzi yekukuvadzwa"echo ine kukosha kwakawanda""kupindira
③Maitiro Ekushandisa
Zvishandiso zveLaser rangefinder, zvishandiso zvekuyera daro zvine chinangwa chimwe chete, masisitimu ekuongorora eindasitiri
2. Kodhi yeNguva yeKushanduka kwePulse (Kodhi yeNguva yeKushanduka kwePulse isina kurongeka kana kuti inoshanduka)
①Nheyo yeUnyanzvi
Nzira iyi yekunyora makodhi inodzora nguva dziri pakati pemapundu elaser kuti dzive dzisina kurongeka kana kuti dzisina kurongeka (semuenzaniso, uchishandisa jenareta remasequence asina kurongeka), pane kugadziriswa. Kusarongeka uku kunobatsira kusiyanisa zviratidzo zvekudzoka uye kuderedza kupindirana kwenzira dzakawanda.
②Zvinhu Zvikuru
Kugona kwakasimba kwekudzivirira kupindira, kwakanakira kuonekwa kwechinangwa munzvimbo dzakaoma
Zvinobudirira zvinodzivisa manzwi emweya
Kuoma kwakanyanya kwekunyora makodhi, zvinoda ma processor ane simba rakawanda
Yakakodzera kuona zvinhu zvakasiyana-siyana nemazvo uye kuona zvinhu zvakasiyana-siyana
③Maitiro Ekushandisa
Masisitimu eLiDAR, masisitimu ekutarisa ekudzivirira UAV/kuchengetedza, masisitimu ekuongorora maroja ne laser uye masisitimu ekuziva zvinangwa
3. Kuchinja Kodhi yePulse (Kodhi yePCM)
①Nheyo yeUnyanzvi
PCM inzira yekushandura masaini edhijitari apo masaini eanalog anotorwa, kuverengwa, uye kunyorwa muchimiro chebinary. Mumasisitimu ekutaurirana nelaser, data rePCM rinogona kutakurwa kuburikidza nelaser pulses kuti ruzivo rutumirwe.
②Zvinhu Zvikuru
Kutapurirana kwakagadzikana uye kuramba ruzha kwakasimba
Inokwanisa kutumira marudzi akasiyana-siyana eruzivo, kusanganisira odhiyo, mirairo, uye data remamiriro ezvinhu
Inoda kuenderana kwewachi kuti ive nechokwadi chekuti inogadziriswa zvakanaka pamugamuchiri
Inoda ma modulators nema demodulators anoshanda zvakanyanya
③Maitiro Ekushandisa
Zviteshi zvekutaurirana neLaser (semuenzaniso, masisitimu ekutaurirana eFree Space Optical), kudzora kure kwelaser yezvikombora/zvombo zvemuchadenga, kudzoka kwedata mumasisitimu elaser telemetry
4. Mhedziso
Sezvo"uropi""yemasisitimu e-laser, tekinoroji yekunyora makodhi e-laser inosarudza kuti ruzivo runotumirwa sei uye kuti sisitimu inoshanda sei zvinobudirira. Kubva kumakodhi ekutanga ePRF kusvika kuPCM modulation yepamusoro, kusarudzwa nekugadzirwa kwemapurogiramu ekunyora makodhi kwave chinhu chakakosha pakuvandudza mashandiro esisitimu ye-laser.
Kusarudza nzira yakakodzera yekunyora makodhi kunoda kutariswa kwakazara kwemamiriro ekushandiswa, huwandu hwezvipingamupinyi, huwandu hwezvinangwa, uye kushandiswa kwesimba resisitimu. Semuenzaniso, kana chinangwa chiri chekuvaka sisitimu yeLiDAR yemugadziri we3D wemaguta, kodhi yepakati yekurova inoshanduka ine simba rakasimba rekudzivirira kuvharika inosarudzwa. Kune zvishandiso zviri nyore zvekuyera daro, kodhi yekudzokorora frequency chaiyo inogona kukwana.
