光学镜头调制传递函数的测试

Test Optics Modulation Transfer Function

为了定量、客观、全面地评价光学镜头的像质,介绍了光学镜头调制传递函数的测试。先简要叙述了测试的原理,并给出计算公式;然后介绍了测试步骤,其中包括固定、穿轴、测试中心视场和测试轴外视场;最后介绍了测试时的注意事项,包括对测试工装的要求、对测试平面的要求和正、负轴外视场测试值相差较大时的处理办法。

In order to quantitatively and objectively and comprehensively evaluate the image quality of optical lenses, optical lenses introduced modulation transfer function tests. First a brief description of the principle of the test, and gives the formula;then describes the test procedure, including a fixed field of view through the shaft, the central visual field test and test-axis;finally introduces considerations tests, including tests tooling requirements, requirements and test plane positive and negative off-axis field test value difference between the larger approach.
