Light-field-camera imaging simulation of participatory media using Monte Carlo method

Abstract In this study, we use the Monte Carlo method to analyze the light-field camera imaging of various participating media (absorbing, scattering and emitting media), along with refocused and sub-aperture images, during the process of reconstructing the temperature field of a high-temperature combustion flame. Hence, the optical field of the participating medium is analyzed. We found that if the participating medium does not have active emission capability, the absorptive and scattering capacity can be regarded as attenuation capacity. However, if the medium has active emission capability, it is difficult to obtain the emission characteristics corresponding to the depth of field through refocusing, and the medium’s temperature field can only be reconstructed using sub-aperture images.
