入射角度和云母钛珠光颜料幻彩色关系的研究

探索了光在云母钛珠光颜料内部的光学行为，对光在颜料内部的传播过程中的能量和传播方向的变化进行了模拟和计算。肉眼观察幻彩类云母钛珠光颜料的随角异色效应，其随角异色的效果通常只有某种单一颜色的变化，比如幻蓝色珠光颜料随角度的变化只会呈现白色到蓝色的变化，而不会出现过渡性的中间色。文章通过对光在颜料内部的能量分析，结合调制度对双光束干涉的影响，合理解释了光线入射角度对颜料幻彩色的影响，计算结果与前期文献中的试验结果相符合。

Study on the Relationship between the Illumination Angle and the Interference Color of Iridescent Mica-Titania Pigment

The optics behavior of light in internal of the mica-titania pigment is investigated and light energy and propagation direction were simulated and calculated. Generally speaking, the angle-dependent effect mica-titania pigment is monotonous detected by naked eyes, but angle-dependent effect only is a single color changes, such as the color changes from the essential white to blue, without any transitional color between the transformation. The influence of incident angle to the interference color of iridescent mica-titania pigment was explained reasonable according to analyze the inter power distribution of light in the pigment and combine with the influence of double-beam interference, the result calculated by the theory is agree with the preceding experimental result.
