二维弥散介质温度场的快速重建

提出了一种利用电荷耦合器件摄像机获取的辐射信息进行二维弥散介质温度场快速重建的新模型. 与现有的温度场重建模型相比，该模型是以逆向Monte Carlo方法为基础，重建速度更快、效率更高，能更好地描述散射介质. 采用了一个精确的二维温度场作为重建对象，结果表明，即使在存在测量误差的情况下，利用此模型重建出的温度场仍能重现原有精确温度场的特征. 关键词： 温度场重建 逆向Monte Carlo 电荷耦合器件摄像机 反问题

Fast reconstruction of two-dimensional temperature distribution in participating medium

An original model was presented for fast reconstruction of two-dimensional temperature distribution in participating medium using radiative information captured by charge-coupled device cameras. Compared with present models for temperature reconstruction, the model developed here is based on backward Monte Carlo method and reconstruction speed is faster, it is more efficient and can describe the scattering medium better. An exact two-dimensional temperature was assumed to be the reconstruction object and results show that even if there are measurement errors, the reconstructed temperature distribution can reproduce the original temperature distribution.
