提出了应用于三维非对称温度场全息层析测量的一种最优松弛因子下有序迭代计算的最大熵重建算法。通过计算机模拟，考察了重建精度与投影方向数及迭代次数的关系。结果表明该算法具有计算效率高，收敛快，尤其适合于少投影数的重建问题。

The maxium entropy reconstructionalgorithm of optimal relaxation parameter and order-iteration calculation is presented. By the computer simulation, the relationshipbetween reconstructiveprecision and views as well as the relationship between reconstructive accuracy and iterations are tested.The results show that this technique has the merits of quick convergence and high computation efficiency with fewer views compared as MART.
