大尺度光学列阵的成像特性

本文由光线光学理论出发,分析了无单元像差的光学元件大尺度列阵的成像特性,得到了较傍轴近似更普适的成像特性变换矩阵,其结果包含了列阵的傍轴近似成像理论.并进一步证明了大尺度平面列阵的成像特性只具有近似的准相位共轭特性,且只有在傍轴近似下才是较完善的准相位共轭成像.该结论与以往理论相比更接近实际,且能更好地解释迄今为止所观察到的实验结果及本文的实验结果.

Imaging properties of large size optical arrays

According to the ray optical theory, the imaging properties of optical arrays are analysed. A general imaging transfer matrix is obtained, which includes a special case of paraxial ray approximation. Furthermore, we show that plane arrays imaging is approximating phase conjuation, and it is the phase conjugation only for the paraxial case. Using a new pseudoconjugator-------------coneshaped corner arrays, the wavefront distortion compensation is demonstrated, and the experimental results are consistent with the theory of this paper.
