The Ray Tracing Math Model was developed to predict the intensity of IR heat energy that could be projected from a halogen lamp, or cluster of lamps, to a target for the purpose of heating the target. The target in this particular case is the shuttle external tank. The mathematical ray trace model developed for this special application can easily be extended to accommodate other optical as well as acoustic ray tracing applications, where the approximation of ideal reflecting surfaces and incoherent waves is appropriate.

Many software packages are available for ray tracing (ray tracing is a technique that has been practiced for centuries). However, only in recent years has the numerical computing power of PCs made it possible to combine Monte Carlo integration techniques with ray-tracing geometry. Even though commercial off-the-shelf software may be available to solve this problem, it was decided that developing the capability from scratch would provide a better solution and one that could be customized to this specific problem.

The current version of the model and software assumes ideal parabolic surfaces and ideal reflectors. This limitation could be improved with more work. However, for the current application, this limitation is not considered a major disadvantage.
