【摘要】 设计了一种适用于拍摄大视角动态全息图的光路，用精心选模的高性能调ＱＮｄ：ＹＡＧ倍频脉冲激光器拍摄了几种动态三维流场的双曝光全息图．在用层析法对双高斯函数的温度场作了模拟验证性计算的基础上，给出了双芯乙醇灯温度场的两个横截面上温度分布的重建结果．更多还原

【Abstract】 An optical system was designed which applies to capturing large aspect angle’s dynamics holographic picture. Using superior Q switching Nd:YAG laser whose mode had been chosen meticulously, some dynamics 3 D flow field’s double exposure hologram was captured. On the base of simulation checking calculation with tomography to double gaussian functional temperature field, the temperature distribution’s reconstruction on the two cross sections of bicore ethyl alcohol lamp’s temperature field was given.更多还原
