Iwindi elimnyama le-infrared for lidar / DMS / OMS / TOF module (1)

Kusuka kumamojula wokuqala we-tof kuya ku-lidar kuya kuma-DMS wamanje, bonke basebenzisa ibhendi eseduze ye-infrared:

I-TOF Module (850nm / 940nm)

I-Lidar (905NM / 1550nm)

I-DMS / OMS (940NM)

Ngasikhathi sinye, iwindi le-Optical liyingxenye yendlela ye-optical ye-detector / receiver. Umsebenzi wayo oyinhloko ukuvikela umkhiqizo ngenkathi udlulisela i-laser ye-wavelength ethile ekhishwe ngumthombo we-laser, kanye nokuqoqa amagagasi akhanyayo aboniswe ngewindi.

Le windi kumele ibe nemisebenzi eyisisekelo elandelayo:

1. Ukubonakala kubonakala kumnyama ukumboza amadivayisi we-opoleelyronic ngemuva kwewindi;

2

3. Inokudlulisela okuhle kweqembu le-laser. Isibonelo, kumshini we-laser evame kakhulu we-905nm, ukudluliselwa kwewindi kubhendi le-905NM kungafinyelela ngaphezu kwama-95%.

I-4. Hlunga ukukhanya okulimazayo, ukuthuthukisa isilinganiso se-Signal-to-Noise sohlelo, futhi uthuthukise amandla okuthola i-lidar.

Kodwa-ke, i-lidar ne-DMS yiminye imikhiqizo yezimoto, ngakho-ke imikhiqizo yewindows ingahlangabezana kanjani nezidingo zokwethembeka okuhle, ukudluliselwa okukhulu kwebhendi yomthombo wokukhanya, nokubukeka okumnyama sekuyinkinga.

I-01. Ukufingqwa kwezixazululo zewindi okwamanje emakethe

Kunezinhlobo ezintathu ikakhulukazi:

Thayipha 1: I-substrate yenziwe ngezinto zokungena ezingena ngaphansi kwe-infrared

Lolu hlobo lwezinto ezibonakalayo lumnyama ngoba lungakwazi ukudonsa ukukhanya okubonakalayo futhi ludlulise amabhendi asondelene, ngokudluliselwa okungama-90% (anjenge-905NM ebhendini eliseduze) kanye nokuthembisa okuphelele okungama-10% acishe abe ngu-10%.
