给出了在单口径片状放大器 (SSA)实验平台上利用哈特曼波前传感器进行热恢复研究的实验结果。结果表明 ,三片长的SSA双程最大热波前畸变约为 1 1λ峰谷 (P V)和 0 .13λ均方根梯度 (RMS) (λ =6 32 8nm)。实验结果与模拟计算结果进行了相互校核 ,两者符合得较好。
The experimental results of heat recovery using Hartmann wavefront sensor on a single-aperture SSA experimental platform are given. The results show that the maximum two-way thermal wavefront aberrations of the three-piece SSA are about 1 1λ peak valley (P V) and 0.13λ root mean square gradient (λ = 6 32 8nm). The experimental results and the simulation results were checked with each other, and the two accord well with each other.
