Abstract: An illumination assembly includes a light source, which is configured to emit optical radiation. A transparency containing a plurality of micro-lenses, which are arranged in a non-uniform pattern and are configured to focus the optical radiation to form, at a focal plane, respective focal spots in the non-uniform pattern. Optics are configured to project the non-uniform pattern of the focal spots from the focal plane onto an object.
