Lub ntsiab kev ua tau zoo ntawm hluav taws xob detectors
(1) Quantum detection efficiency (DQE) yog qhov ua tau zoo uas lub tshuab ntes hloov cov teeb liab tawm tswv yim rau hauv cov teeb liab tawm. Lub teeb liab input zog thiab lub teeb liab tso zis lub zog feem ntau yog sawv cev los ntawm tus naj npawb ntawm cov hais los yog photons. Quantum efficiency muaj feem xyuam rau hom kev ntes, hom thiab lub zog ntawm qhov xwm txheej rays, thiab lwm yam. Nws cuam tshuam ncaj qha rau cov duab zoo.
(2) rhiab heev yog hais txog qhov tsawg kawg nkaus input teeb liab lub zog yuav tsum tau rau lub detector tso zis ib tug detectable teeb liab. Cov khoom kuaj pom zoo muaj rhiab heev rau ib qho photon.
(3) Lub dynamic ntau yam yog qhov ntau yam uas lub teeb liab tso zis ntsuas ntsuas yog proportional rau lub teeb liab input, tseem hu ua linear range.
(4) Lub suab nrov yog hais txog cov teeb liab tso tawm los ntawm cov teeb liab uas tsis yog tawm tswv yim.
(5) Lub sij hawm daws teeb meem yog lub sij hawm tsawg kawg ntawm ob qhov xwm txheej uas nyob ib sab uas tuaj yeem daws tau los ntawm tus ntes.
(6) Lub zog daws teeb meem yog lub peev xwm ntawm lub tshuab ntes kom paub qhov txawv ntawm qhov sib txawv ntawm lub zog, feem ntau muab faib los ntawm ib nrab qhov siab dav ntawm cov zis pulse ntawm qee lub zog los ntawm qhov siab pulse.
(7) Spatial daws teeb meem yog lub peev xwm ntawm tus ntes los daws qhov tsawg tshaj plaws geometric cov ntsiab lus, thiab nws feem ntau yog qhia los ntawm spatial zaus (modulation hloov pauv muaj nuj nqi txo rau 0.2) los yog unsharpness. Nws yuav tsum raug sau tseg tias qhov kev daws teeb meem spatial yog nyob ntawm cov txheej txheem tshwj xeeb uas ua haujlwm.
