在10℃～230℃温差下, 对大气相干长度r0分别采用夏克哈特曼的到达角起伏法、差分像运动法、波面法三种测量法和四象限探测器进行了测试和对比；对折射率结构常量C2n及闪烁功率谱分别采用夏克哈特曼和光电倍增管进行对比.实验结果表明：对于r0, 在强湍流时四象限探测器比夏克哈特曼的稳定性明显降低, 且对夏克哈特曼三种方法, 差分像运动法可克服设备抖动等问题, 但引入了方向上不一致的问题, 波面法可有效避免该问题；对于C2n, 夏克哈特曼比光电倍增管测量更稳定, 拟合相关系数高达0.96；对于闪烁功率谱, 由于噪音影响, 在200℃时夏克哈特曼比光电倍增管测得的最大频率高15 Hz；最后, 通过对夏克哈特曼子孔径的闪烁功率谱分析得出, 若同一子孔径入射光强不在CCD响应的线性区间时无法准确测量闪烁功率谱, 否则可通过不同子孔径可完成湍流均匀性的测量.这将为湍流池提供最优的测试方法及理论依据.

During the temperature difference of 10℃~230℃, three kinds of ShackHartman measuring methods are used to contrast atmospheric coherence length r0 with quadrant detector(QD), and ShackHartman(SH) and photomultiplier tube(PMT) respectively are applied to contrast refractive index structure parameter C2n with scintillation power spectrum. The experimental results show that: for r0 , the stability of QD decreases more obviously than SH when there is strong turbulence, and for three ShackHartman methods, DIMM overcomes problems such as device jitter but brings in problem of inconsistency in direction which wave front method can avoid; for C2n, SH is more precise than PMT which fitting correlation coefficient is up to 0.96; for scintillation power spectrum, the maximum frequency SH tested is 15 Hz higher than that of PMT when it is 200℃ influenced by noise; through the analysis of ShackHartman subaperture scintillation power spectrum, the scintillation power spectrum is not able to be measured precisely and different subapertures accomplish the measurement turbulence uniformity when the same subaperture incident intensity is not in the CCD response linear interval. The results will provide an optimal test method and theoretical basis for turbulence cell.
