Theauto duhu waldi kwalkwali kwalkwali ne na kariya ta atomatik wanda aka yi da ƙa'idodi kamar optoelectronics, injina, da photomagnetism.Jamus ta fara ƙaddamar da DZN4647T.7 ta hanyar lantarki mai sarrafa murfin waldadi da ma'aunin gilashi a cikin Oktoba 1982, kuma ƙa'idar BS679 da Burtaniya ta yi shelar a 1989 ya nuna lokacin da garkuwar haske ta canza daga yanayin haske zuwa yanayin duhu yayin walda.A farkon shekarun 1990 ne kasar Sin ta fara kera kwalkwali mai canza launin walda mai amfani da wutar lantarki ta atomatik.
Na farko, tsarin ya ƙunshi sassa biyu: babban jikin kwalkwali da tsarin canza haske.Babban jikin kwalkwali yana da kai, tare da gyare-gyaren allura na ABS, mai nauyi, mai ɗorewa, ana iya daidaita shi daga sassa daban-daban guda uku, yana iya daidaitawa da nau'ikan nau'ikan kai.Tsarin hasken ya haɗa da firikwensin haske, sarrafa kewayawa, bawul ɗin haske crystal ruwa, da tacewa.
Na biyu, ka'idar kariya, The karfi baka radiation generated a lokacin waldi aka sampled da haske firikwensin, jawo da kula da kewaye, da kuma fitarwa aiki ƙarfin lantarki na kula da kewaye da aka kara da ruwa crystal haske bawul, da kuma ruwa crystal haske bawul. canje-canje daga yanayin gaskiya zuwa yanayin da ba a sani ba a ƙarƙashin aikin wutar lantarki, kuma watsawar ultraviolet yana da ƙasa sosai.Wani ɓangarorin hasken infrared ta cikin bawul ɗin hasken kristal na ruwa yana ɗaukar wani tacewa.Da zarar an kashe hasken baka, firikwensin hasken ba ya sake fitar da sigina, da'irar sarrafawa ba ta sake fitar da wutar lantarki mai aiki ba, kuma bawul ɗin hasken kristal na ruwa ya dawo zuwa yanayin bayyananne.
