knife-edge ambiguity function 刀刃型模糊函数
Secondly, based on the optical knowledge such as edge spread function > line spread function and point spread function etc. , motion-blurred point spread function can be assessed through knife-edge function curve, according to the motion-blurred image.
其次，本文在刃边函数、线扩散函数、点扩散函数及光学传递函数等光学知识的基础上，通过检测运动模糊图像的刃边函数曲线，直接由运动模糊图像估算出运动模糊点扩散函数，提高了运动模糊点扩散函数的估算精度。

The OTF (Optical Transfer Function) of an optical system can be evaluated by the Fourier Transform of the first derivative of the optical image of an knife-edge (object).
对光学系统输出刀口像的一阶导数做傅里叶变换，可以得到该系统的光学传递函数（OTF）。
We also analyse different interpolating methods , knife edge, gray-draw, height, angle which effect Modulated Transfer Function(MTF).
我们主要分析了不同的插值方法，刀口，灰度拉伸，高度，角度对MTF的影响。
