| 摘 要： | 报道以一维平面阶梯条形纯位相结构，用等光程补偿的物理概念出发，计算了单线与双线象的衍射光学元件的多种构形，获得了与理想衍射线象符合的光强分布；同时发现双线象时会出现噪音光强小峰，这在精确成象时仍是要设法避免的．

| Abstract: | In this paper, we report the calculation of single line-image and double lineimage for various configuration of diffractive optical element (DOE), which were designed as one- dimensional plane configuration of bar- shaped pure- phase from the principle of the optical equal- path compensation. The calculated light intensity distributions are in agreement with which from the ideal diffraction disk. There are some weaker noise-light peaks between the double line-image. It should be improved for high precision imaging. |
