| 描述了一种用于分析三维微结构干涉式结构色的光线追迹算法。该算法将光线追迹与光学干涉原理相结合，用于计算不同出光方向的干涉光谱，并依据色度学原理计算干涉光谱对应的结构色。同时该算法可以对参与干涉的光线进行溯源，从而将光谱特征与光线在微结构中的传播轨迹联系起来，并分析了入射光束空间相干性对干涉光谱的影响。以微尺度凹界面结构为例，分析了其结构色产生的原理，解决了目前该领域中多种干涉机制难以独立分析的问题，为基于多次反射干涉原理的微尺度结构色研究提供了便捷、高效和普适的仿真平台。 |

| This article describes a ray-tracing algorithm for analyzing the interference-based structural color of three-dimensional microstructures. The algorithm integrates ray tracing with the principles of optical interference to calculate the interference spectra in different emission directions and to determine the corresponding structural colors based on the principles of colorimetry. Additionally, the algorithm can trace the rays involved in the interference, thereby linking the spectral characteristics with the propagation paths of the rays within the microstructures. It is also capable of analyzing the impact of the spatial coherence of the incident light beam on the interference spectra. Taking microscale concave surface structures as an example, the article analyzes the principle of their structural color formation, addressing the challenge of independently analyzing multiple interference mechanisms in this field. This algorithm provides a convenient, efficient, and universal simulation platform for the study of microscale structural colors based on multiple reflection interference principles. |
