Point-spread functions, line-spread functions, and edge-response functions associated with modulation transfer functions (MTFs) of the form exp[-(omega/omega(c))(n)] are tabulated for values of the MTF index (n) in the range from n = 1.0 to n = 2.0, in steps of 0.10. The MTFs are also tabulated in this range. Measurements of any one of these four image transfer functions which agree with the tabulated valves for a given set of MTF parameters (omega(c,)n) allow the other three functions to be estimated by using these tables.
与形式为exp[-(ω/ω(c))(n)]的调制传递函数（MTF）相关的点扩散函数、线扩散函数和边缘响应函数，针对MTF指数（n）在n = 1.0至n = 2.0范围内、步长为0.10的值制成表格。MTF在该范围内也制成表格。对于给定的一组MTF参数（ω(c),n），这四个图像传递函数中任何一个的测量值若与表格中的值相符，则可通过使用这些表格来估计其他三个函数。
