Vanhu vazhinji vangashamisika kuti sei mamodule e laser rangefinder achiuya mumhando dzakasiyana dze wavelengths. Chokwadi ndechekuti, kusiyana kwe wavelengths kunoitika kuti zvienderane nezvinodiwa zvekushandisa nezvirambidzo zvehunyanzvi. Laser wavelength inokanganisa zvakananga mashandiro esystem, kuchengetedzeka, uye mutengo. Heino tsananguro yakadzama yezvikonzero:
1. Mhedzisiro yeWavelength paHunhu hweMuviri hweRangefinding
(1) Kuderedza Kushanda Kwemhepo Nekufambisa Mashandiro
Kutapurirana kweLaser kunokonzerwa nekunyudzwa kwemhepo uye kupararira kwayo, izvo zvese zvinoenderana zvakanyanya nehurefu hwemafungu.. Marefu mapfupi eWave (semuenzaniso, 532nm):eruzivo rwakakosha zvikuru mukupararira (rayleigh kuparadzira). Munzvimbo dzine guruva, mhute, kana mvura inonaya, kudzikira kwemvura kwakawanda, zvichiita kuti dzisakodzere kushandiswa kure. Mid-Range Wavelengths (semuenzaniso, 808nm, 905nm):hHadzina kunyorova zvakanyanya mumhepo, zvichiita kuti dzive sarudzo huru dzekushandisa pakutsvaga ruzivo, kunyanya pakushandisa panze. Marefu eWavelength (semuenzaniso, 1535nm, 1550nm):shaipindi mvura inonyungudika pasi pemamiriro ezvinhu akati asi inoratidza kupararira kushoma uye simba rakawanda, yakakodzera daro refu nenzvimbo dzakagadzirwa.
(2) Hunhu hweKuratidza Nzvimbo Dzinonangwa
Kuonekwa kwema wavelengths elaser panzvimbo dzakatarwa kunokanganisa mashandiro ekutsvaga nzvimbo..
PfupiwmarefupInoshanda zvakanaka nezvinangwa zvinopenya zvakanyanya asi ine mwenje mudiki panzvimbo dzakasviba kana dzakaomarara.rhashawmarefuoinopa kugona kuchinjika zvakanaka pazvinhu zvakasiyana-siyana uye inowanikwa mumamodule ekutsvaga nzvimbo.pzvinopa mukana wekupinda zviri nani panzvimbo dzisina kusimba, zvichiita kuti dzive dzakakodzera kumepu yenzvimbo uye mamiriro ezvinhu akaomarara.
2. Kuchengetedzwa Kwemaziso uye Kusarudzwa Kwehurefu Hwemafungu
Ziso remunhu rinonzwa zvikuru chiedza chinoonekwa (400-700nm) uye chiedza che near-infrared (700-1000nm). Marambi eLaser ari muzvikamu izvi anogona kutarisa pa retina uye kukonzera kukuvara, zvichiita kuti simba ridzorwe zvakanyanya uye kuderedza mashandisirwo emagetsi uye kugona kubuda kwemagetsi.wmarefu (semuenzaniso, 1535nm, 1550nm)ari skana simba ravo richitorwa ne cornea ne lens, zvichidzivirira kusangana zvakananga ne retina. Izvi zvinoderedza zvakanyanya njodzi dzekuchengetedza, zvichiita kuti ma wavelength aya ave anokosha pakutsvaga nzvimbo dziri kure nemauto uye dzine simba guru.
3. Kuoma Kwehunyanzvi uye Mutengo
Kuomarara uye mutengo wemamodule e laser rangefinder zvinosiyana zvakanyanya zvichienderana nehurefu hwewavelength.
- 532nm (Green Lasers): Inowanzo gadzirwa nema-frequency-double infrared lasers (1064nm). Maitiro aya haashande zvakanaka, anoda kupisa kwakanyanya, uye anodhura zvakanyanya.
- 808nm, 905nm (Near-Infrared Lasers): Batsirwa netekinoroji ye semiconductor laser yakakura, ichipa kushanda kwepamusoro uye mutengo wakaderera, zvichiita kuti ive yakakodzera zvigadzirwa zvemhando yepamusoro zvevatengi.
- 1535nm, 1550nm (Fiber Lasers): Inoda mafiber lasers akasarudzika uye ma matching detectors (semuenzaniso, InGaAs). Mamodule aya anodhura zvakanyanya.
4. Zvinodiwa pakushandisa muzviitiko zvakasiyana
Zve skupisa-drubatsiromchiyero, 532nm ne905nm sarudzo dzakanaka kwazvo. Kunyangwe mhedzisiro yekupararira yakakosha pahurefu hwemafungu mapfupi, haina simba rakawanda padaro diki. Pamusoro pezvo, ma laser e905nm anopa chiyero chekushanda uye mutengo, zvichiva sarudzo huru yemamodule erangefinder.Kune long-drubatsiromKuyera: 1064nm uye 1550nm marefu emvura akakodzera, sezvo marefu emvura anowedzera simba uye anopinda zvinobudirira, zvakanakira mashandisirwo emaindasitiri nemauto anoda kuyerwa kwenguva refu uye kwakanyatsojeka.Kune high-lchiedza-ikupindiraenzvimbo, Mawavelength e1550nm anobudirira mumamiriro ezvinhu akadaro, sezvo asinganyanyi kukanganiswa nekukanganiswa kwezuva. Izvi zvinoita kuti pave nechiratidzo chakakwirira pakati peruzha nechiedza chakasimba, zvichiita kuti akwanise kushandiswa pakushandisa radar yekunze uye michina yekutarisa.
Netsananguro iyi, unofanira kunge wava nekunzwisisa kwakadzama kwekuti sei mamodule eraser rangefinder achiuya muhurefu hwakasiyana hwema wavelength. Kana uchida mamodule eraser rangefinder kana kuti uchida kudzidza zvakawanda, inzwa wakasununguka kutibata chero nguva!
