由于Gabor同轴数字全息适用于透过光能量远大于目标遮挡能量，因此，针对小目标的不同横向位置的再现性能研究具有重要的应用价值。进行了不同横向位置的2.52 THz Gabor同轴全息成像实验，将Tukey窗函数和角谱法结合实现二维再现，并对再现结果进行对比分析。实验结果表明，提出的算法抑制了孔径效应且整幅图像对比度也有所提高；靠近探测器中心部位的目标较处于探测器边缘附近的目标再现性能略好。

Gabor on-axis digital holography is suitable for the situation that light transmission energy is much more than the energy blocked by the target. Therefore, the reconstruction study on the small target at different lateral positions has important application value. The experiments on 2.52 THz Gabor on-axis holographic imaging at different lateral positions are conducted, the Tukey window function and the angular spectral method are combined to realize two-dimensional reconstruction, and the results are compared and analyzed. The experimental results show that the algorithm proposed inhibits the aperture effect and also improves the contrast ratio of the whole image. The reconstruction performance of the target close to the central position of the detector is slightly better than that near the edge.
