An original technique was presented for noncontact three-dimensional temperature field measurement in a participating medium using radiative information captured by a CCD camera. This technique was based on the backward Monte Carlo method and was faster and more efficient than traditional techniques based on the forward Monte Carlo method. A numerical simulation case was adopted to validate the technique. It was found that the technique was capable of reconstructing the three-dimensional temperature field well, even with noisy input data.
