VI. Juyin Halittar Fasaha da Yanayin Gaba

A cikin fasahar ji na zamani, LiDAR (Gano Haske da Range) yana aiki a matsayin "idanu" na injuna, yana fahimtar duniyar 3D daidai ta hanyar fitar da hasken laser da karɓar hasken. Waɗannan "idanu" suna buƙatar "rufin kariya" mai haske don kariya - wannan shine Murfin Tagar LiDAR. Ba wai kawai wani ɓangare ne na gilashi na yau da kullun ba amma wani ɓangaren fasaha mai zurfi wanda ya haɗa kimiyyar kayan aiki, ƙirar gani, da injiniyan daidaito. Aikinsa kai tsaye yana ƙayyade daidaiton ji, kewayon, da amincin tsarin LiDAR.

I. Ayyukan Ciki: Bayan "Kariya"
Murfin tagar LiDAR garkuwa ce mai faɗi ko kuma mai siffar ƙwallo wadda ta lulluɓe ɓangaren waje na firikwensin LiDAR. Manyan ayyukansa sun haɗa da:

1. Kariyar Jiki:Yana ware ƙura, danshi, mai, har ma da tarkace masu tashi yadda ya kamata, yana kare abubuwan ciki (misali, na'urorin fitar da haske ta laser, na'urorin gano abubuwa, madubai masu daukar hoto).
2. Rufe Muhalli:A matsayin wani ɓangare na ginin, yana samar da hatimin hana iska shiga tare da sassan gini don cimma ƙimar IP da ake buƙata (misali, IP6K7/IP6K9K), yana tabbatar da aiki mai kyau a cikin mawuyacin yanayi kamar ruwan sama, dusar ƙanƙara, da guguwar yashi.
3. Watsawar gani:Babban aikinsa mafi mahimmanci shine barin na'urorin laser na musamman masu tsawon zango su ratsa ta yadda ya kamata ba tare da wata matsala ba. Duk wani toshewa, tunani, ko rashin daidaituwa kai tsaye yana rage daidaito da ingancin girgije mai ma'ana.

II. Kayan Aiki Na Musamman: Yaƙin Gilashi;
Zaɓin kayan yana nuna aikin rufin tagogi. Babban masana'antu yana amfani da kayan da aka yi da gilashi, galibi nau'i biyu:
1. Gilashin Silica Mai Haɗaka

• Halaye:Babban abin da ake amfani da shi a fannin kera motoci da masana'antu. An yi shi da silica mai tsafta, yana ba da kyawawan halaye na gani.

• Ribobi:

1. Kyakkyawan watsawa daga UV zuwa IR tare da ƙarancin sha sosai.
2. Ƙarancin yawan faɗaɗa zafi yana jure yanayin zafi mai tsanani (-60°C zuwa +200°C) ba tare da nakasa ba.
3. Taurin kai mai yawa (Mohs ~ 7), yana da juriya ga gogewa daga yashi/iska.

• Aikace-aikace:Motocin da ke cin gashin kansu, manyan AGVs na masana'antu, suna binciken LiDAR.

2. Gilashin Sapphire

• Halaye:Na'urar α-alumina mai siffa ɗaya ta roba, wadda ke wakiltar aiki mai matuƙar girma.

• Ribobi:

1. Taurin kai mai tsanani (Mohs ~9, na biyu bayan lu'u-lu'u), kusan babu karce.
2. Daidaitaccen watsawar gani, juriyar zafin jiki mai yawa (ma'aunin narkewa ~ 2040°C), da kuma daidaiton sinadarai.

• Kalubale:Yana da tsada sosai, yana da wahalar sarrafawa (yana buƙatar goge lu'u-lu'u), da kuma yawan amfani.
• ;Aikace-aikace:Ma'aunin sojoji masu inganci, na sararin samaniya, da kuma na matuƙar daidaito.

III. Rufi: Fasaha ta asali da ke mayar da Dutse zuwa Zinariya

Ko da kuwa wane irin substrate ne, rufin yana da mahimmanci don biyan buƙatun gani na LiDAR masu tsauri:

• ;Rufin Anti-Reflection (AR):Mafi mahimmancin Layer. An adana shi ta hanyar shafa mai (misali, e-beam evaporation, magnetron sputtering), yana rage hasken saman zuwa <0.5% a tsawon tsayin daka da aka yi niyya, yana ƙara watsawa daga ~92% zuwa >99.5%.
• Rufin Hydrophobic/Oleophobic:Yana hana manne ruwa/mai, yana kiyaye tsabta a cikin ruwan sama ko gurɓataccen muhalli.
• ;Sauran Rufin Aiki:Fina-finan cire abubuwa masu zafi (ta amfani da ITO), yadudduka masu hana tsayawa, da sauransu, don buƙatu na musamman.

IV. Ma'aunin Aiki Masu Muhimmanci

Lokacin zaɓar ko kimanta murfin taga na LiDAR, mai da hankali kan waɗannan ma'auni:

1. Transmittance @ Target Ra'ayin:Kashi na hasken da aka watsa a tsawon aikin LiDAR (misali, >96% a 905nm/1550nm bayan rufewar AR).
2. Daidaiton Band:Dole ne ya dace da tsawon hasken laser (905nm/1550nm); ya kamata a rage hasken (<0.5%).
3. Daidaiton Siffar Fuskar:Ya kamata kurakuran lanƙwasa da daidaito su kasance ≤λ/4 (λ = tsawon laser) don guje wa karkacewar haske.
4. ;Tauri da Juriyar Sakawa:An auna ta hanyar sikelin Mohs; yana da mahimmanci don dorewa na dogon lokaci.
5. Juriyar Muhalli:

• Juriyar Ruwa/Ƙura: Mafi ƙarancin ƙimar IP6K7.
• Zafin jiki: Matsakaicin aiki yawanci -40°C zuwa +85°C.
• Feshin UV/gishiri don hana lalacewa.

V. Yanayin Aikace-aikace

Kusan duk tsarin LiDAR da aka fallasa ga muhalli yana buƙatar murfin taga:

• Motocin da ke da kansu:An ɗora shi a kan rufin gida, bumpers, ko gefe, yana fuskantar fuskantar yanayi da hasken UV kai tsaye.
• Tsarin Taimakon Direba Mai Ci Gaba (ADAS):An haɗa shi cikin jikin abin hawa, yana buƙatar jituwa ta kyau.
• Masana'antu AGVs/AMRs:Aiki a cikin rumbunan ajiya/masana'antu masu haɗarin ƙura da karo.
• Binciken & Nesa Mai nisa:Tsarin hawa da ke hawa sama/abin hawa wanda ke jure canjin tsayi da canjin yanayin zafi.

Kammalawa;

Ko da yake wani abu ne mai sauƙi na zahiri, murfin tagar LiDAR yana da mahimmanci don tabbatar da "hangen nesa" bayyananne da aminci ga LiDAR. Ci gabanta ya dogara ne akan haɗin kai mai zurfi na kimiyyar abu, na gani, hanyoyin rufewa, da injiniyan muhalli. Yayin da zamanin tuƙi mai cin gashin kansa ke ci gaba, wannan "taga" zai ci gaba da bunƙasa, yana kare ainihin fahimta ga injuna.
