In the present paper, threshold value method of diffractedintensity is put forward to process the test data, so the boundary of defect is legible.
采用衍射强度阈值法对测试数据进行处理,使得缺陷边界清晰可辨。

The diffracted light intensity on axis of a Spatial light Modulator (SLM) with Multi-level Phase Fresnel Zone Plate (MPFZP) is studied by diffraction optical method.
用衍射光学方法研究了加有多级相位菲涅尔波带片(MPFZP)的空间光调制器(SLM)的轴上衍射光强。
