摘　　要：根据对比度传递函数的定义,推导分析了线列光纤传像束对比度传递函数(CTF)的表达式,拟定了测量方案.在检测过程中,采用局部视场扫描测量方法,选用10/0.25的显微物镜,3#鉴别率板(分辨率为1.875 lp/mm),测得平均 CTF 值为0.52,仿真值为0.66.With the definition of the contrast transfer function,contrast linear transfer function (CTF) expression of line-array fiber-optics image bundles is established.A measuring method about the CTF of line-array fiber-optic image bundles is put according to the theoretically.During the measurement a local view scan measuring method is adopted,by 10/0.25 micro objective and 3# resolution test pattern (resolution factor is 1.875 lp/mm.),measures the CTF average is 0.52 and simulation result is 0.66.
