1) nonparaxial aberration
非傍轴像差
1.
Firstly,the paraxial approximation condition must be satisfied in the recording process of the hologram,otherwise a nonparaxial aberration will be produced in the reconstruction process.
对数字无透镜傅里叶变换全息图直接采用逆傅里叶变换进行物场的数值重建时,需要满足两个条件:第一,全息图的记录过程必须满足傍轴近似条件,否则再现过程中会产生非傍轴像差;第二,记录全息图时物平面与参考点光源到全息图记录平面的距离必须相等,否则再现过程中会产生离焦像差。
2) paraxial imagery
傍轴成像
3) non-paraxial
非傍轴

For studying the character of Hermite-sine-Gaussian (HSiG) beam in non-paraxial case,based on the theory of the second intensity moment and a series of complex calculations,the results of the far-filed divergence angle,waist width and M~2 factor of non-paraxial Hermite-sine-Gaussian beams are derived,and the relationship of them versus the acentric parameters are studied by calculation and plot.

非傍轴理论
1.
The nonparaxial theory is applied to analyze the color blur of the annular aperture rainbow hologram where the paraxial approximation is invalid due to the largeincident angle of object wave.
基于非傍轴理论，对普通共轭再现及利用孔径共轭技术再现两种情况下大角度环形孔径周视彩虹全息图的色模糊进行了系统地分析，导出了相应的表达式，并证明了大参考角及孔径共轭技术的采用并不会使最终像的色模糊与普通彩虹全息图相比发生明显变化，从而为该类全息图的应用提供了理论依据。
