We introduce a novel approach in optical engineering by combining Dammann gratings with binary Fresnel zone plates to create a unique hybrid optical element with enhanced energetic efficiency of its focal spots. Traditionally, binary Fresnel zone plates focus light at multiple points with varying intensities, while Dammann gratings are renowned for their efficient and uniform light splitting capabilities. Our innovation lies in merging these two elements and generating a binary circular Dammann (varying along the radial direction) Fresnel zone plate that concentrates most of the incident light into a small and desired number of focused points with equal intensities, rather than distributing light’s energy non-equally across multiple points. This novel design significantly enhances the efficiency and precision of light manipulation. It opens new possibilities in applications requiring high-intensity focal points, such as in advanced medical imaging and in accurate scientific measurements. By redefining the conventional roles of these optical elements, our research contributes an advancement to the field, paving the way for innovative solutions in various optical applications.

使用二元圆形达曼菲涅尔波带板增强成像

我们在光学工程中引入了一种新颖的方法，将达曼光栅与二元菲涅尔波带板相结合，创建出一种独特的混合光学元件，其焦点的能量效率得到了提高。传统上，二元菲涅尔波带板将光聚焦在不同强度的多个点上，而达曼光栅以其高效且均匀的分光能力而闻名。我们的创新在于合并这两个元件并生成二元圆形达曼（沿径向方向变化）菲涅尔波带板，该菲涅尔波带板将大部分入射光集中到少量且所需数量的具有相同强度的聚焦点，而不是将光的能量分布为非均匀分布。 - 多个点均等。这种新颖的设计显着提高了光操纵的效率和精度。它为需要高强度焦点的应用开辟了新的可能性，例如先进的医学成像和精确的科学测量。通过重新定义这些光学元件的传统作用，我们的研究推动了该领域的进步，为各种光学应用中的创新解决方案铺平了道路。
