Abstract An ever-increasing need for accurate and fast techniques of modelling radiative transfer is driving the necessity to improve current and also develop new techniques. Any improvements would benefit furnace design where the main transport of energy at high temperatures in annealing materials is radiation [1], medical diagnostics utilising light propagation through biological tissue [2], efficient light distribution rendering in computer generated animation [3], modelling solar heat transfer through the different layers of earth’s atmosphere [4] and many astrophysics related problems.

Determining the optical properties of media has a plethora of applications in industries which need to determine the components of samples, such as air quality monitoring and water composition determination.

The aim of this thesis is to investigate the use of two-stream approximations of the Discrete Ordinates method in computing radiative transfer. The main investigation is into the use of Discrete Ordinates methods in determining the optical properties of a media if the reflectance and transmittance is known. By observing the use of the Inverse method on a mixture of polystyrene particles in water, its application can be observed in a potential practical setting.
