The results indicate that the information about phase change of the input object function can be obtained under given conditions, when it is illuminated by an incoherent quasi - monochromaticsource.
分析表明，在一定条件下，可得到输入物函数相位变化率分布的信息。

In order to suppress the coherent artigact noise, a method of image differentiation by means of monochromatic incoherent line source is described.
为了压抑相干噪声，本文采用单色非相干线光源进行图像微分。
