N'otu oge ahụ, windo anya bụ akụkụ nke ụzọ anya anya nke onye nchọpụta / nnata. Isi ọrụ ya bụ ichekwa ngwaahịa ahụ mgbe ọ na-ebufe laser nke otu ogologo wavele ogologo nke isi iyi laser na-ebunye, na ịnakọta ebili mmiri ọkụ kwekọrọ na windo.
Window a ga-enwerịrị ọrụ ndị a bụ isi:
1. Anya na-egosi oji iji kpuchie ngwaọrụ optoelectronic n'azụ windo;
2. N'ozuzu elu reflectivity nke anya window dị ala na-agaghị eme ka doro anya echiche;
3. Ọ nwere ezi nnyefe maka eriri laser. Dịka ọmụmaatụ, maka ihe nchọpụta laser 905nm na-ahụkarị, nnyefe nke windo na band 905nm nwere ike iru karịa 95%.
4. Na-enyocha ọkụ na-emerụ ahụ, melite ogo mgbaàmà na mkpọtụ nke usoro ahụ, ma welie ikike nchọpụta nke lidar.
Otú ọ dị, LiDAR na DMS bụ ngwaahịa ụgbọ ala, ya mere, otú ngwaahịa windo nwere ike isi mezuo ihe ndị a chọrọ maka ezigbo ntụkwasị obi, nnyefe dị elu nke eriri ọkụ, na ọdịdị ojii aghọwo nsogbu.

Ụdị 1: A na-eji ihe ntinye infrared mee ihe ahụ
Ụdị ihe a bụ oji n'ihi na ọ nwere ike ịmịnye ọkụ a na-ahụ anya ma na-ebufe eriri infrared dị nso, na-ebufe ihe dị ka 90% (dị ka 905nm na nso-infrared band) na n'ozuzu reflectivity nke ihe dị ka 10%.
Nke a na ụdị ihe nwere ike iji infrared ukwuu transperent resin substrates, dị ka Bayer Makrolon PC 2405, ma resin mkpụrụ nwere adịghị mma bonding ike na ngwa anya film, enweghị ike iguzogide siri ike gburugburu ebe obibi nnwale nnwale, na-enweghị ike plated na ukwuu pụrụ ịdabere na ITO transperent Conductive film (eji maka eletrịkt na defogging), otú a na-adịghị na-produkter nke na-adịghị eji windo na-emepụta ihe na-adịghị eme ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe na-adịghị na windo. chọrọ kpo oku.
Ị nwekwara ike ịhọrọ SCHOTT RG850 ma ọ bụ Chinese HWB850 iko ojii, ma ọnụ ahịa nke ụdị ojii a dị elu. N'iji iko HWB850 dịka ọmụmaatụ, ọnụ ahịa ya karịrị okpukpu 8 karịa nke enyo anya nkịtị nke otu nha, na ọtụtụ n'ime ụdị ngwaahịa a enweghị ike ịgafe ọkọlọtọ ROHS ya mere enweghị ike itinye ya na windo lidar mepụtara.
Ụdị 2: iji infrared transmissive ink
Ụdị infrared penetrating ink a na-amịkọrọ ìhè a na-ahụ anya ma nwee ike ibunye eriri infrared dị nso, na-ebufe ihe dịka 80% ruo 90%, na mkpokọta nnyefe dị ala. Ọzọkwa, mgbe ink jikọtara na ngwa anya mkpụrụ, ihu igwe na-eguzogide enweghị ike ịgafe siri ike ụgbọ ala ihu igwe nguzogide chọrọ (dị ka elu okpomọkụ ule), otú infrared penetrating ink na-akasị eji na ngwaahịa ndị ọzọ nwere ala ihu igwe chọrọ dị ka smart phones na infrared ese foto.
Ụdị 3: iji nzacha anya oji kpuchie
Ihe nzacha mkpuchi ojii bụ ihe nzacha nwere ike igbochi ọkụ a na-ahụ anya ma nwee oke mbufe na band NIR (dị ka 905nm).
A na-eji silicon hydride, silicon oxide na ihe nkiri dị gịrịgịrị ndị ọzọ mee ihe nzacha ojii, a na-akwado ya site na iji teknụzụ sputtering magnetron. A na-eji ya arụ ọrụ kwụsiri ike na nke a pụrụ ịdabere na ya ma nwee ike ịmepụta ya. Ka ọ dị ugbu a, ihe nkiri nzacha ojii a na-ahụkarị na-adịkarị n'ụdị ihe nkiri yiri nke ihe nkiri na-egbu ọkụ. N'okpuru usoro ihe nkiri silicon hydride magnetron sputtering usoro, ihe a na-echekarị bụ ibelata nnabata nke silicon hydride, ọkachasị nnabata nke band infrared dị nso, iji hụ na nnyefe dị elu na band 905nm ma ọ bụ ụgbụ lidar ndị ọzọ dị ka 1550nm.
