Using photon mapping for multispectral modeling of scenes within THz range

Wojciech Gołębiowski


A method for simulation of appearance of large, geometrically modeled environment in THz range is presented. Photon mapping technique is used with Monte Carlo photon sampling. Propagation of radiation within the scene is simulated for multiple discrete radiation frequencies, various materials are being modeled with emissivity, reflectivity and attenuation characteristics. The results are used to predict the answer of passive, multispectral terahertz detector matrix.
