本文用数值方法研究了无透镜可变焦全息多重投影在倾斜平面上的可行性。我们已经开发了无透镜可变焦全息单投影使用缩放衍射，计算不同采样间距的平行平面之间的衍射。这种可变焦全息投影的结构非常简单，因为它不需要透镜;然而，它只将单个图像投影到平行于全息图的平面上。本文提出的无透镜可变焦全息投影系统能够将多幅图像同时投影到倾斜的平面上。
This paper numerically investigates the feasibility of lensless zoomable holographic multiple projections to tilted planes. We have already developed lensless zoomable holographic single projection using scaled diffraction, which calculates diffraction between parallel planes with different sampling pitches. The structure of this zoomable holographic projection is very simple because it does not need a lens; however, it only projects a single image to a plane parallel to the hologram. The lensless zoomable holographic projection in this paper is capable of projecting multiple images onto tilted planes simultaneously.
