提出了一种将表面信息融入光线映射方法的新方法。这种方法计算物理光学表面和目标平面上的辐照度，而不是通常平坦或半球形的虚拟表面，从而得到反映系统真实几何形状的映射关系。在一个极端的例子中(离轴60°)证明了该方法的稳健性，该方法的一致性高达82%。
A novel approach to incorporate surface information into the ray mapping method is proposed. This method calculates irradiance at the physical optical surface and target plane instead of the usually flat or hemispherical dummy surface, resulting in a mapping relationship which reflects the true geometry of the system. The robustness of the method is demonstrated in an extreme example (60° off axis) where the uniformity is as high as 82%.
