摘要
介绍了MTF的概念,以及MTF在印刷版材感光乳剂中的应用,并以这个为基础,重点分析了正弦波,线扩散函数的傅立叶转换和相干光处理3种方法,特别讨论图像传递过程中的非线性影响。通过对比,指出了3种方法各自的特点以及测量MTF所需的不同条件。最后总结出了MTF精确度的影响因素,能够在合适的条件下给出一个最有效的印刷版材感光乳剂的调制传递函数,从而保证印刷图像传递的品质。
The conception of MTF and its application in photo emulsion was introduced. The sine wave method, Fourier transformation of the line spread function, and coherent light processing method were analyzed based on MTF. The nonlinearity of image transformation was discussed. The character of each method and the different applied condition was put forward. Factors influencing the precision of MTF were summarized, and an accurate and effective MTF of photo emulsion in given condition can be provided to achieve high quality of image transfer.
