Abstract

Real-time diagnosis of the radiative properties of participatory media, such as flames, is very difficult due to their spatial and temporal complexity. In this paper, we propose a new method to simultaneously reconstruct gas and carbon soot properties using a multispectral light-field camera. Hyperspectral light-field imaging is performed on two targets (a rectangular participating medium and a flame) to analyze the spectral imaging effect of gas-solid radiative properties in the mid-infrared band. The two-color method combined with the nearest-neighbor filtering method was used to reconstruct the medium temperature and carbon soot absorption coefficients, which helps yield the gas mole fractions (H₂O and CO₂) for a specific mid-infrared band and reconstruct their actual distributions.
