摘　　要：为实现传统红外成像系统与红外偏振成像系统探测能力的比较,基于系统的最小可分辨温差和最小可分辨偏振度差,分别建立了二者的作用距离模型,讨论了非理想探测器的参数对系统探测能力的影响,并设计了相应实验,验证了建立模型的可靠性,为实际探测中不同应用场景下的成像系统选择提供了参考。To compare the detection capabilities of traditional infrared imaging systems and infrared polarization imaging systems,the operating distance models of the systems were established based on the minimum resolvable temperature difference and the minimum resolvable polarization degree difference.The effects of parameters of non-ideal detectors on the detection capabilities of the systems were discussed,and the corresponding experiments were designed to verify the reliability of the established models.This provides a reference for the selection of imaging systems in different application scenarios in actual detection.
