摘　　要：通过计算机仿真技术,针对不同的光路分布结构进行了气体浓度场二维分布重建模拟,研究了光路的分布与重建精度的联系。并通过计算归一化平均绝对距离判据比较不同光路分布下的重建精度,得到重建精度较高的光路分布形式。结果表明,在光路数量较少的情况下,提高光路的利用率可以提高重建精度。通过计算评估优化后的光路分布下的重建精度,验证了结论的正确性。The two-dimensional distribution of gas concentration field under different distributions of light path is simuiated using the computer simulation technology, and the connection between the distribution of light path and the reconstruction accuracy is researched. Reconstruction accuracy in different distributions of light path is compared by calculating the normalized mean absolute distance criterion, and the light path distribution of better reconstruction accuracy is got. The results show that improving the utilization rate of laser path can enhance the reconstruction accuracy in the case of less light path. And the validity of results are verified by calculating the reconstruction accuracy of the optimized light path distribution.
