Abstract:
The calculation of the eikonal from the condition of focusing into a line with designed energy distribution reduces to a first-order differential equation solved for the derivative. We design a DOE and non-diffractive refractive optical elements to produce a line-segment focus and a circular-arc focus. The simulation shows that the optical elements produce high-quality focal lines.

Key words:
eikonal, optical element, curvilinear coordinates, intensity, light field, line density.
