Chifukwa Chiyani Pali Ma Laser Rangefinder Module okhala ndi Mafunde Osiyanasiyana?

Anthu ambiri angadabwe kuti chifukwa chiyani ma module a laser rangefinder amabwera mosiyanasiyana. Chowonadi ndi chakuti, kusiyanasiyana kwa mafunde amphamvu kumachitika kuti athe kulinganiza zosowa zamagwiritsidwe ntchito ndi zovuta zaukadaulo. Laser wavelength imakhudza mwachindunji magwiridwe antchito, chitetezo, ndi mtengo. Naku kufotokozera mwatsatanetsatane zifukwa zake:

1. Zotsatira za Wavelength pa Mawonekedwe Athupi a Rangefinding

(1) Atmospheric Attenuation and Transmission Performance

Kutumiza kwa laser kumakhudzidwa ndi kuyamwa kwamlengalenga ndi kubalalitsidwa, zonse zomwe zimadalira kwambiri kutalika kwa mafunde.. Mafunde Aafupi (monga 532nm):ekukumana ndi kubalalitsidwa kwakukulu (rayleigh kubalalitsa). M'malo afumbi, chifunga, kapena mvula, kuchepetsedwa kumakhala kokulirapo, zomwe zimapangitsa kuti zikhale zosayenera kugwiritsa ntchito mtunda wautali. Mid-Range Wavelengths (mwachitsanzo, 808nm, 905nm):hkukhala ndi mayamwidwe ochepa mumlengalenga ndi kubalalikana, zomwe zimawapangitsa kukhala zisankho zodziwika bwino za ofufuza, makamaka ntchito zakunja. Mafunde Aatali (mwachitsanzo, 1535nm, 1550nm):skukhudzidwa ndi kuyamwa kwa nthunzi wamadzi pansi pazifukwa zina koma kumawonetsa mphamvu zochepa zomwazikana komanso zokhazikika, zoyenera mtunda wautali ndi malo apadera.

(2) Mawonekedwe Owoneka Pamawonekedwe Azolowera

Kuwonekera kwa laser wavelengths pamalo omwe chandamale kumakhudza magwiridwe antchito.   

Wachidulewavelengthspsinthani bwino ndi mipherezero yowunikira kwambiri koma osawoneka bwino pamalo amdima kapena oyipa. Pakati-rangewavelengthsoamapereka kusinthika kwabwino pazida zosiyanasiyana ndipo ndizofala pama module opeza. Mafunde Aataliplowetsani malowedwe abwino pa malo oyimba, kuwapangitsa kukhala abwino popanga mapu a mtunda ndi zochitika zovuta.

2. Chitetezo cha Maso ndi Kusankhidwa kwa Wavelength

Diso la munthu limakhudzidwa kwambiri ndi kuwala kowoneka (400-700nm) komanso kuwala kwapafupi ndi infrared (700-1000nm). Miyendo ya laser m'magulu awa imatha kuyang'ana pa retina ndikuwononga, kufunikira kuwongolera mphamvu mwamphamvu ndikuchepetsa mawonekedwe ogwiritsira ntchito komanso kuchuluka kwa zotulutsa. Wautaliwkutalika (mwachitsanzo, 1535nm, 1550nm)ndi smphamvu zawo zimatengedwa ndi cornea ndi lens, zomwe zimalepheretsa kukhudzana mwachindunji ndi retina. Izi zimachepetsa kwambiri ziwopsezo zachitetezo, zomwe zimapangitsa kuti mafundewa akhale ofunika kwa asitikali ndi mphamvu zapamwamba zopeza mtunda wautali.

3. Kuvuta kwaukadaulo ndi Mtengo

Kuvuta ndi mtengo wa laser rangefinder modules zimasiyana kwambiri kutengera kutalika kwa kutalika.  

- 532nm (Green Lasers): Amapangidwa ndi ma frequency-double infrared lasers (1064nm). Njirayi imakhala ndi mphamvu zochepa, zofunikira zowonongeka kutentha, komanso ndalama zambiri.

- 808nm, 905nm (Near-Infrared Lasers): Pindulani ndi ukadaulo wokhwima wa semiconductor laser, womwe umapereka magwiridwe antchito apamwamba komanso otsika mtengo, kuwapangitsa kukhala abwino pazogulitsa zamagulu ogula.

- 1535nm, 1550nm (Fiber Lasers): Amafuna ma lasers apadera a ulusi ndi zowunikira zofananira (mwachitsanzo, InGaAs). Ma module awa ndi okwera mtengo kwambiri.

4. Zofuna Kugwiritsa Ntchito Muzochitika Zosiyana

Za skwambiri-dgawomkuchepetsa, 532nm ndi 905nm ndi zosankha zabwino kwambiri. Ngakhale zotsatira zobalalitsa zimakhala zazikulu pamafunde amfupi, zimakhala ndi zotsatira zochepa pamatali aafupi. Kuphatikiza apo, ma laser a 905nm amapereka magwiridwe antchito komanso mtengo wake, kukhala chisankho chodziwika bwino chamitundu yosiyanasiyana.Za lmonga-dgawomKuwongolera: 1064nm ndi 1550nm wavelengths ndi oyenera kwambiri, popeza kutalika kwa mafunde kumalimbitsa mphamvu ndikulowa mogwira mtima, koyenera pamafakitale ndi asitikali omwe amafunikira kuyeza kwautali komanso kolondola kwambiri.Za hayi-lusiku-ikusokonezaemalo, Mafunde a 1550nm amapambana mumikhalidwe yotere, chifukwa sakhudzidwa kwambiri ndi kusokoneza kwa dzuwa. Izi zimatsimikizira chiŵerengero chapamwamba cha ma signal-to-phokoso pansi pa kuwala kwamphamvu, kuwapanga kukhala oyenera radar yakunja ndi zida zowunikira.

Ndi kufotokozeraku, muyenera tsopano kumvetsetsa mozama chifukwa chake ma module a laser rangefinder amabwera mosiyanasiyana. Ngati muli ndi zosowa zama module a laser rangefinder kapena mukufuna kudziwa zambiri, omasuka kulankhula nafe nthawi iliyonse!
