摘　　要：从传像方式上给出了光锥的理论传递函数,并提出了利用星点像分析测试其MTF的方法,通过具体实验给出了MTF的测试结果.测试结果表明,合理的选取测试组件参数,可以得到光锥在较大频率范围内的光学传递函数(>100lp/mm).从MTF趋势上看,测试结果与理论推导呈一致性.Theoretic optical transfer function (OTF) of cone fiber optic bundle are presented, by analyzing of image transfer manner and digital simulating, a OTF test method with spotlight image analyzing is proposed and experiment results agree well with theoretic analyzing. OTF of cone fiber optic bundle can be obtained at a large frequency range (larger than 100 lp/mm), by rational setting of test system parameter.
