修改后的phase函数，把它的门限值换为pi，使用更方便(The modified phase function, the threshold for it to pi, the use of more convenient)

说明：  基于matlab的衍射模拟，在毕业设计的时候顺便参考做的，有问题的话欢迎指出(Matlab simulation based on the diffraction, when the way in the graduate design reference do have problems, then welcome to point out)

实现彩色图象的读取,以及回度图象的读取,及相关的变换(Achieve color image reading, and reading back of the picture, and the associated transformation)
