Nhau - Black Infrared Window yeLiDAR/DMS/OMS/ToF module(1)

Kubva kune ekutanga maToF modules kusvika kune yazvino DMS, vese vanoshandisa iri pedyo-infrared bhendi:

TOF module (850nm/940nm)

LiDAR (905nm/1550nm)

DMS/OMS (940nm)

Panguva imwecheteyo, hwindo remaziso chikamu chenzira yekuona ye detector / receiver. Basa rayo guru ndere kuchengetedza chigadzirwa uchiendesa laser yeawavelength chaiyo inoburitswa neiyo laser sosi, uye kuunganidza inoenderana inoratidzira mafungu emwenje nepahwindo.

Iri hwindo rinofanirwa kuve neanotevera akakosha mabasa:

1. Inoratidzika seyakasviba kuvhara michina ye optoelectronic kuseri kwehwindo;

2. Iyo yakazara pamusoro pekutarisa kwehwindo remaziso yakaderera uye haizokonzeri kufungidzira kuri pachena;

3. Iine yakanaka transmittance yelaser band. Semuenzaniso, kune yakajairika 905nm laser detector, iyo transmittance yehwindo mu905nm bhendi inogona kusvika kupfuura 95%.

4. Sefa chiedza chinokuvadza, vandudza chiratidzo-ku-ruzha reshiyo yegadziriro, uye wedzera kugona kuona kwe lidar.

Nekudaro, LiDAR neDMS zvese zvigadzirwa zvemotokari, saka sei zvigadzirwa zvemahwindo zvinogona kusangana nezvinodiwa zvekuvimbika kwakanaka, kufambisa kwepamusoro kwebhendi remwenje, uye kutaridzika dema rave dambudziko.

01. Pfupiso yemhinduro dzemahwindo parizvino pamusika

Kune kunyanya marudzi matatu:

Type 1: Iyo substrate inogadzirwa ne infrared inopinda zvinhu

Rudzi urwu rwezvinhu dema nekuti rinogona kutora mwenje unooneka uye kuendesa pedyo-infrared mabhendi, ine transmittance inosvika 90% (senge 905nm iri padyo-infrared bhendi) uye kutaridzika kwese kunosvika gumi%.

Rudzi urwu rwezvinhu runogona kushandisa infrared yakanyanya kujeka resin substrates, senge Bayer Makrolon PC 2405, asi resin substrate ine urombo hwekubatanidza simba neiyo optical firimu, haigone kumirisana nehutsinye hwekuedzwa kwemamiriro ekunze, uye haigone kuputirwa neakavimbika ITO transparent Conductive firimu (inoshandiswa electrification uye defogging), saka rudzi urwu runowanzo shandiswa mune isina kuvharwa mahwindo, saka rudzi urwu runowanzo shandiswa mune isina kuvharwa mahwindo. hazvidi kudziyisa.

Iwe unogona zvakare kusarudza SCHOTT RG850 kana Chinese HWB850 girazi dema, asi mutengo werudzi urwu rwegirazi dema wakakwira. Tichitora girazi reHWB850 semuenzaniso, mutengo waro unodarika ka8 pane yegirazi regirazi rakajairwa rehukuru hwakafanana, uye mazhinji emhando iyi yechigadzirwa haagone kupfuudza iyo ROHS standard uye nekudaro haigone kuiswa kune yakawanda-yakagadzirwa lidar windows.

Rudzi rwechipiri: kushandisa infrared transmissive inki

Iri rudzi rweinfrared inopinda ingi inotora chiedza chinooneka uye inogona kutumira pedyo-infrared mabhendi, ine transmittance ingangoita 80% kusvika 90%, uye iyo yese transmittance level yakadzikira. Uyezve, mushure mekunge ingi yasanganiswa neiyo optical substrate, kuramba kwemamiriro ekunze hakugone kupfuudza zvakaomesesa mota yemamiriro ekunze zvinodiwa (senge tembiricha yekuyedza), saka infrared inopinda ingi dzinonyanya kushandiswa mune zvimwe zvigadzirwa zvine yakaderera mamiriro ekunze zvinodiwa senge smart mafoni uye infrared makamera.
Rudzi rwechitatu: uchishandisa dema rakavharwa optical sefa
Iyo dema yakavharwa sefa sefa inogona kuvhara mwenje unooneka uye ine yakakwirira transmittance paNIR bhendi (senge 905nm).

Iyo nhema yakavharidzirwa sefa yakagadzirwa nesilicon hydride, silicon oxide uye zvimwe zvitete zvemufirimu zvinhu, uye inogadzirirwa uchishandisa magnetron sputtering tekinoroji. Iyo inoratidzirwa nekugadzikana uye yakavimbika kuita uye inogona kuve yakawanda-yakagadzirwa. Parizvino, akajairwa dema optical sefa mafirimu anowanzo tora chimiro chakafanana neyakagadzika firimu. Pasi peyakajairwa silicon hydride magnetron sputtering film forming process, yakajairika kufunga kudzikisa kunyudzwa kwesilicon hydride, kunyanya kutorwa kweiyo iri pedyo-infrared bhendi, kuve nechokwadi chekufambisa kwakanyanya mu905nm bhendi kana mamwe lidar mabhendi akaita se1550nm.
