照相材料正弦波调制传递函数测试方法研究

由于照相材料的调制传递函数是表征照机影象质量的一项重要指标，因而吸引了众多科研人员展开了对照相材料调制传递函数理论的研究。作者也对照相材料调制传递函数的理论作了进一步研究，并在该理论的基础上设计并建立了一种更为新颖、简便的正弦波调制传递函数测试方法。实验结果表明：用该方法测试得到的调制传递函数值精度高、重复性好。本文详细介绍了该的基本原理、测试软件构成、样品及重复性试验。

On the Measurement Method for Sinusoidal Wave Modulated Transferring Function of Photographic Material

There have been much research work done on the modulated transferring function of photographic material because of its importance as an index attributing the quality of photograph.In this work, based on the theory of modulated transferring function. We designed a new as well as convenient method to measure the sinusoidal wave modulated transferring function of photographic material. The experimental results of this method were more accurate and reproducibility of the measuring results is described.
