The structure of Fresnel zone plates is considered as a binary carrier of complex modulation functions. Due to the Fourier-transforming roperties of this particular carrier, any original object can be reconstructed with a simple monochromatic point source using no additional optics. An analysis of modulated zone plates (MZP) verifying their Fourier-transforming and imaging properties is given. experiments were performed with several types of computer-drawn MZP's. Results illustrating the flexibility of this method are in good agreement with theory. The simple method of reconstructing and scaling the object intensity distribution, the high efficiency, as well as he resistance against high laser intensities show the MZP to be a convenient tool for laser micromachining of patterns with optional shape.
菲涅耳波带片的结构被视为复调制函数的二元载体。由于该特定载体的傅里叶变换特性，使用简单的单色点光源无需额外光学元件就能重建任何原始物体。给出了对调制波带片（MZP）的分析，验证了它们的傅里叶变换和成像特性。用几种类型的计算机绘制的MZP进行了实验。说明该方法灵活性的结果与理论非常吻合。重建和缩放物体强度分布的简单方法、高效率以及对高激光强度的抗性表明，MZP是用于激光微加工任意形状图案的便捷工具。
