针对儿童斜视辅助治疗的色散问题, 提出了利用微棱镜阵列组消除压贴三棱镜中的色散现象的设计方案。通过压贴三棱镜平移光线, 用微棱镜阵列组进行色散补偿, 设计了一个新颖的组合光学系统。阐述了微棱镜阵列组色散补偿的基本原理, 并利用几何光学软件仿真了组合光学系统的色散、透过率等光学参数。点列图以及扩散函数图等仿真结果表明, 微棱镜阵列对于减少压贴三棱镜的色散有较明显的效果。

To solve the dispersion problems in the press-on prism, this paper proposes a method that using micro prism array to compensate dispersion phenomenon of the press-on prism. In this paper, a new combined optical system is formed, using the press-on prism to translate light and using the micro prism array to compensate dispersion. Additionally, the basic principle of dispersion compensation is introduced, and the geometric optical software is used to simulate the dispersion and transmittance of the optical system. All the analysis figures, including spot diagram, PSF and so on, show an obvious effect in using micro prism to compensate dispersion of the press-on prism.
