edge spread function造句

• By using knife edge as object , and cmos sensor as device for image analyzing , we get edge spread function from the image and use differential operation and fft to obtain modulation transfer function of the lens , then its image quality is known
  以刀口作为目标物，以cmos作为图像分析器件，从图像中获取刀口函数，经微分和fft运算，得到成像镜头的mtf (调制传递函数) ，从而得知其成像品质。
• The system is on the basis of fourier optics . by using knife edge as object , cmos sensor as device for image reception , we get edge spread function from the image histogram and use differential operation and fft to achieve mtf of the lens , then its image quality is obtained
  本系统以傅立叶光学为依据，以刀口为目标物，以cmos为图像接收器件，采用独特的算法，从刀口图像的灰度直方图中获得其刀口边缘函数，经微分和fft运算，得到待测镜头的mtf ，从而得知其成像品质。
