ABSTRACT:
An atmospheric refraction profile is determined using an imaging system positioned at a location that is simultaneously within line-of-sight of two celestial light sources. A variety of active or passive methods can be employed to cause the line-of-sight to vertically traverse through a refractive portion of an atmosphere. Images of the two celestial light sources are captured as the line-of-sight vertically traverses through the refractive portion of the atmosphere. Each such image indicates an apparent distance between the two celestial light sources. The apparent distances are used to determine refraction angles.
