Paper Abstract

Refraction effects can alter the appearance of an object near the horizon, resulting in sometimes severely distorted images of the object. The amount of distortion is determined by the curved trajectory that light rays follow through the atmosphere. Variations in the index of refraction, due to among others variations in the temperature of the atmosphere, are responsible for this curving of light rays. There are several models that can be used for to calculate the curvature of the light rays. Lehn has developed a simple model that traces light rays through a refracting atmosphere. The atmosphere is represented by spherical layers in which the temperature is taken constant. The intersections of the light ray and the boundaries are calculated in terms of the temperature and pressure of the atmosphere in this layer.
