全息体视图技术是一种成熟的裸眼三维显示技术,很多基于全息体视图技术的产品已经成功地实现了商业化并带来较好的视觉体验。但在实际应用中,全息体视图技术仍存在着再现像的视角无法满足观察需要、打印高质量的全息图所需采样图像过多、光学实验结果缺少模拟结果与其对照等问题。很多国内外研究小组对这些问题进行了深入研究。在此介绍了应用最广泛的两种全息技术,并综述了近年来在扩大全息体视图视场角、减少全息体视图所需要的采样数量以及全息体视图的数值重构等方面的研究进展。

Holographic stereogram technology is a three-dimensional display technology that can be used with the naked eye. Several holographic stereogram products have been successfully commercialized and have realized amazing visual experiences. However, in practical applications, several problems remain, such as an inadequate field of view (FOV) in the reconstructed image applications, excessive number of sampled images required to print a high-quality holographic stereogram, and lack of simulation results used for comparison with experimental results. In recent years, several research groups have conducted in-depth research on these issues. This study introduces the two most widely used holographic stereogram techniques, and then summarizes recent progresses in enlarging the FOV of a holographic stereogram, reducing the number of required samples,and numerical reconstruction of holographic stereograms.
