To address the limitations of unsound physical models and the lack of compensation mechanisms in existing multi-degree-of-freedom programmable lighting methods, we proposed a novel multi-degree-of-freedom programmable lighting approach. The maximum deviation of single-wavelength spectral distribution curves before and after compensation was reduced by 2 times, and energy distribution uniformity was improved by 19.42 times. The wavelength scanning, intensity encoding, and broadband target spectral modulation performances were verified. The spectral modulation errors for CIE standard illuminants A and D65 were -1.78% and -0.86%, respectively. This research lays the foundation for high-precision optical detection and analysis, enabling applications in biomedical and material fields.
为了解决现有多自由度可编程照明方法中物理模型不合理以及缺乏补偿机制的局限性，我们提出了一种新颖的多自由度可编程照明方法。补偿前后单波长光谱分布曲线的最大偏差降低了2倍，能量分布均匀性提高了19.42倍。验证了波长扫描、强度编码和宽带目标光谱调制性能。CIE标准照明体A和D65的光谱调制误差分别为-1.78%和-0.86%。本研究为高精度光学检测与分析奠定了基础，可应用于生物医学和材料领域。
