A micro-optic cell design with a regularly spaced micro-lens array, having a series of randomly positioned lenslets that have been digitally overwritten, wherein the overwritten area is greater than 0 up to 100 percent fill, and wherein a light shaping diffuser pattern is placed on top of the lenslets of the micro-optic cell.

A wavefront sensor for determining a wavefront of an impinging light beam includes a microlens array formed by nanoimprint lithography. Each microlens of the microlens array includes a plurality of concentric ridges separated by concentric grooves. A ratio F of a width of the concentric ridges to a pitch p of the concentric ridges is a function of a radial distance r from a microlens center to the concentric ridges.
