An algorithm for the design of imaging systems with circular symmetry that exhibit high resolution as well as extended depth of field for polychromatic incoherent illumination is presented. The approach provides a significant improvement over a publication [1] where the design was carried for a single wavelength. The approach is based on searching for a binary phase pupil mask that provides imaging with the highest cut-off spatial frequency, while assuring a desired contrast value over a given depth of field. Simulations followed by experimental results are provided.
提出了一种用于设计具有圆对称的成像系统的算法,该系统对于多色非相干照明展现出高分辨率以及扩展的景深。与一篇文献[1]相比,该方法有显著改进,在文献[1]中设计是针对单一波长进行的。该方法基于搜索一个二元相位光瞳掩模,该掩模能提供具有最高截止空间频率的成像,同时在给定景深范围内确保所需的对比度值。给出了仿真结果及实验结果。
