The Fourier transform characteristics of off-axis hololens was discussed, which was made by using a dot light source and an inclined parallel light.
利用一点光源和一束倾斜平行光拍摄了一种离轴全息透镜，并对其傅里叶变换特性进行了分析。
In this paper, Based on diffracted wave diffusion theory another analysis method about the condition keeping reconstructed image separate from backdrop light for off axis hologram is given.
本文从衍射波扩散出发，提出了另一种分析离轴型全息图再现象与背景光分离条件的方法。
An off-axis fill light also technically isn't a true fill light, since it cannot lighten all shadows visible to the camera - just those from its direction.
一个离轴填充光也不是一个真正专门填充光，因为它不能减轻所有阴影可见的相机——只是那些从它的方向。
Many therefore use a fill light which strikes their subject from a direction which partially opposes the main light (" off-axis ").
许多因此使用填充光并袭击他们的专业方向部分反对主要光(“偏离”)。
However, off-axis fill has its own disadvantages, with perhaps the worst being that one now has to worry about the appearance of shadows from the fill light.
然而，离轴填充有其不足之处，也许最坏的就是一个现在要担心的样子填充光暗处。
On the other hand, an on-axis fill light might be too restricting, and has a higher chance of producing direct reflections off the subject.
另一方面，一个上填充光可能太的限制，有更高的几率产生直接反映了这个话题。
