分析了MTF测量的正弦光栅法和倾斜刃边法，总结了2种方法的优缺点，并分别用2种方法对一简单成像系统的MTF进行了测量，然后将结果与ISO标准进行了对比。结果表明，用倾斜刃边法测量不仅操作简单、易控制，测量结果也更精确。

Sinusoidal grating method and slanted edge method of MTF measurement was analyzed. The advantages and disadvantages of the two methods were summarized. MTF of simple imaging system was then measured using the two methods and the compared with ISO standard. The results showed that slanted edge method is not only easy operation and simple control but also has higher accuracy of measurement results.
