より正確な空気の屈折率のメモ

Posted at

背景

物理的により正確な光学シミュレーションをしたい.

空気(air)は屈折率(ior, index of refraction) 1.0 にすることが多いが, 物理的には気圧や温度で変化する.

式などの情報

P. E. Ciddor. Refractive index of air: new equations for the visible and near infrared, Appl. Optics 35, 1566-1573 (1996)

実装

上の refractiveindex.info でリンクされているもの.

および batoid(C++ backed optics ray tracer)が参考になります.
