Simplified Geometric Approach to Freeform Beam Shaper Design

<div>Fried geometry for the <i>i</i>, <i>j</i> ray. Wavefront gradient components Φ<sub><i>x,ij</i></sub> and Φ<sub><i>y,ij</i></sub> are obtained from (<a href="https://static.hindawi.com/articles/ijo/volume-2020/2896593/figures/#EEq26">26</a>) and serve to calculate wavefront phase Φ<sub><i>ij</i></sub> distribution.</div>
