Dareemaha iftiinka ambientwaxay inta badan ka kooban tahay qaybaha indhaha.Qaybaha xasaasiga ah ayaa si degdeg ah u horumaray, noocyo badan, oo si ballaaran loo isticmaalo.Dareemka iftiinka deegaanku wuxuu ogaan karaa xaaladda iftiinka ku hareeraysan wuxuuna ku wargelin karaa qalabka wax lagu sameeyo inuu si toos ah u hagaajiyo iftiinka dambe ee kormeeraha si loo yareeyo isticmaalka awoodda alaabta.Dhanka kale, dareenka iftiinka ambient wuxuu ka caawiyaa bandhigga sawir jilicsan.Marka dhalaalka deegaanku sareeyo, soo-bandhigida dareeraha ah ee crystal-ka ee isticmaalaya dareeraha iftiinka ambient ayaa si toos ah ula qabsan doona dhalaalka sare.Marka deegaanka dibaddu uu madoobaado, bandhiga waxa lagu hagaajin doonaa dhalaal hoose.

Fogaanta iftiinka waxay u dhowdahay chip-dareemaha -WH APS 4530A waa nooc ka mid ah iftiinka beddelka dhijitaalka ah.Waxay isku daraysaa dareemayaasha iftiinka deegaanka ee horumarsan, dareemayaasha horumarsan iyo nalalka LED-ka infrared ee waxtarka leh.Shaandheeyaha ayaa lagu dhex dhisay si uu u xakameeyo infrared-ka, wuxuuna bixiyaa spectrum u dhow falcelinta indhaha bini'aadamka.ALS waxay ku shaqayn kartaa mugdi ilaa iftiinka qoraxda, cabirka ogaanshaha ee la doortayna waa ilaa 40dB.Wax soo saarka laba-channel (indhaha bini'aadamka iyo cad), si ALS ay u yeelato saamiga iftiinka wanaagsan ee xaaladaha iftiinka kala duwan.Shaandheeyaha 940nm wuxuu ku dhex dhisan yahay dareemayaasha (PS) ee iftiinka deegaanka.Sidaa darteed, PS waxay ogaan kartaa iftiinka infrared reflex, kaas oo leh saxsanaan sare iyo iska caabin heer sare ah.WH4530A waxay leedahay shaqo joojin barnaamij la samayn karo, waxayna leedahay daah-fur ku salaysan ALS iyo PS.

Dareemayaasha iftiinka deegaanku waxay leeyihiin iftiin yar oo mugdi ah, jawaab-celin iftiin hoose, dareen sare, iyo isbeddel toosan oo leh iftiinka iftiinka hadda;dhisay-in dual-xasaasi ah element, attenuation si toos ah u dhow infrared, spectral jawaab celin u dhow qalooca shaqada indhaha aadanaha (madow: qalooca jawaabta indhaha aadanaha , Buluug: Qallooca jawaabta caabbinta indhaha, cagaar: qalooca jawaabta iftiinka ambient);Tixgelinta kale ee tixgelin kale marka la dooranayo dareemaha iftiinka ku habboon waa in la doorto dareeme leh jawaab-celin ku habboon.PIN-ka caadiga ah ee Photosami diode ama iska caabbinta indhaha (daasiif ama firfircoon) lafteedu waxay leedahay jawaab celin muuqaal oo aad u ballaaran, oo ay ku jiraan fallaadhaha IR iyo xitaa fallaadhaha UV.
