在许多情况下,自适应光学元件可用于光束转向。当光束通过透镜时,可以在三维体积内扫描所得到的焦点。在这篇文章中,我们介绍的表达式来描述的最大距离,焦点可以转向使用可变形反射镜与连续相位分布,限制在其梯度或振幅。此外,对于液晶空间光调制器(SLM),一个解析的方法来描述由于相位缠绕和像素化的强度降低的转向焦点。通过计算SLM上被相位缠绕占据的总面积,我们可以估计没有被引导到焦点的光的比例。因此,我们推导出一个表达式的3-D体积内,我们可以引导一个焦点,给出了一个允许的强度减少。计算结果与实验结果吻合较好。
There are many situations where adaptive optic elements are useful for beam steering. When the beam is passed through a lens, the resulting focus may be scanned within a three-dimensional volume. In this article, we introduce expressions to describe the maximum distance to which a focus may be steered using a deformable mirror with a continuous phase distribution, limited either in its gradient or amplitude. Additionally for liquid crystal spatial light modulators (SLMs), an analytic approach is developed to describe the intensity reduction of a steered focus due to phase wrapping and pixellation. By calculating the total area on the SLM taken up by phase wrapping, we can estimate the proportion of light that is not directed to the focus. Thus, we derive an expression for the 3-D volume within which we may steer a focus given a permissible reduction in intensity. The results compare favorably with experiment.
