Inzwa yokukhanya kwe-ambientikakhulukazi yakhiwe izingxenye ze-optical.Izingxenye ze-photosensitive zithuthuke ngokushesha, izinhlobo eziningi, futhi zisetshenziswa kabanzi.Inzwa yokukhanya kwemvelo ingabona isimo sokukhanya esizungezile futhi yazise i-chip yokucubungula ukuze ilungise ngokuzenzakalelayo ukukhanya kwangemuva kwemonitha ukuze kuncishiswe ukusetshenziswa kwamandla komkhiqizo.Ngakolunye uhlangothi, inzwa yokukhanya kwe-ambient isiza isibonisi ngesithombe esithambile.Uma ukukhanya kwemvelo kuphezulu, isibonisi sekristalu esiwuketshezi sisebenzisa inzwa yokukhanya kwe-ambient sizojwayela ngokuzenzakalelayo ekukhanyeni okuphezulu.Uma indawo yangaphandle imnyama, isibonisi sizolungiswa sibe ukukhanya okuphansi.
Ibanga elikhanyayo liseduze ne-sensor chip -WH APS 4530A iwuhlobo lokukhanya kuya kusiguquli sedijithali.Ihlanganisa izinzwa zokukhanya zemvelo ezithuthukisiwe, izinzwa ezithuthukisiwe nezibani ze-LED ze-infrared ezisebenza kahle kakhulu.Isihlungi sakhelwe ngaphakathi ukuze sicindezele i-infrared, futhi sinikeza i-spectrum eseduze nokusabela kwamehlo omuntu.I-ALS ingasebenza ngaphansi kobumnyama kuya ekukhanyeni kwelanga, futhi ububanzi obukhethiwe bucishe bube ngu-40dB.Ukukhishwa kwesiteshi esikabili (iso lomuntu futhi kucace), ukuze i-ALS ibe nesilinganiso esihle sokukhanya ngaphansi kwezimo ezihlukene zokukhanya.Isihlungi esingu-940nm sakhiwe -inzwa (PS) yokukhanya kwemvelo.Ngakho-ke, i-PS ingakwazi ukubona ukukhanya kwe-infrared reflex, okunembayo okuphezulu nokumelana okuhle kakhulu.I-WH4530A inomsebenzi wokuphazamiseka ohlelekayo, futhi ine-threshold-based lag ye-ALS ne-PS.
Izinzwa zokukhanya kwemvelo zinezinzwa ezincane ezimnyama, ukusabela kokukhanya okuphansi, ukuzwela okuphezulu, nezinguquko zomugqa ngokukhanya kokukhanya kwamanje;isakhi esakhelwe ngaphakathi esine-dual -sensitive, i-attenuation ezenzakalelayo eduze ne-infrared, impendulo ye-spectral eduze nejika lomsebenzi weso lomuntu (elimnyama: ijika lejika lokuphendula iso lomuntu , Okuhlaza okwesibhakabhaka: Ijika lokuphendula lokumelana ne-Optical, oluhlaza: ijika lokuphendula elikhanyayo elizungezile);Okunye ukucatshangelwa kokunye ukucatshangelwa lapho ukhetha inzwa yokukhanya efanelekile ukukhetha inzwa enempendulo efanelekile ye-spectrum.I-PIN Evamile ye-Photoami diode noma ukumelana nokubona (i-passive noma esebenzayo) ngokwayo inobubanzi obubanzi kakhulu bokusabela okubonwayo, okuhlanganisa imisebe ye-IR ngisho nemisebe ye-UV.
