摘　　要：在不同照度、对比度靶标和夜视兼容等条件下比较了超二代和三代像增强器的分辨力。对于性能基本相同的超二代和三代像增强器,同等照度条件下三代像增强器分辨力更佳,且当照度低于1×10^(-3)lx、对比度小于50%时,差别加大。在夜视兼容条件下,超二代像增强器的光谱匹配度较低,分辨力差距增加1组。在夜视兼容条件下,超二代像增强器的光谱匹配度较低,进一步加大了分辨力差距。在实际使用中,对于无月星光、夜视兼容或低对比度目标条件,同等性能参数的三代像增强器比超二代像增强器更具优势。For the super second generation(Gen2+)and third generation(Gen3)IITs,the reso-lution was compared under different illumination,contrast targets and NVIS lighting compatibility.With basically the same performance,Gen3 IIT had better resolution under the same illumination,especially under illumination below 1×10^(-3)lx and contrast below 50%.Under NVIS lighting compatibility condition,the spectrum matching performance of Gen2+IIT was lower,which furtherly increased the resolution gap with 1 group.In actual applications with moonless starlight,NVIS lighting compati-bility and low contrast target conditions,Gen3 IIT with the same performance parameters was much better than Gen2+IIT.
