英文摘要	High-sensor SNR and high extinction ratio (ER), which are often contradictory requirements for nanowire-filter-based polarimetric imaging systems, aid in attenuating polarimetric imaging system errors. Expressions were derived to analyze their attenuation effects and then simplified using photoelectronic numbers received by super-pixels (PNRS). The first-derivative ratios of PNRS and ER were calculated to compare their attenuation effects. Mathematical models and experiments conducted using polarimetric imaging systems with various ERs and PNRSs indicate that systems with low PNRS and high ER exhibit a polarization error affected more by the attenuation effect of the PNRS than that of the ER. When the system ER is higher than 28, the attenuation effect of the PNRS is higher than that of the ER. Thus, system error attenuation is a trade-off between sensor SNR and ER.
