We report the first experimental results, to our knowledge, with fractal zone plates
implemented in a liquid-crystal display. Our results largely agree with theory for the axial
irradiance distribution of these lenses. The dependence of the shape and size of the focus
points on critical design parameters is discussed. Additional unpredicted features are also
described.
