Abstract
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.
Claims20
An optical element comprising one or more micro-optic unit cells;
- wherein each micro-optic unit cell is comprised of one or more lenslets;
- wherein each lenslet has a boundary shape;
- wherein the lenslets are configured in a regularly spaced micro-lens array (MLA);
- wherein the lenslets are overwritten with randomly placed lenses (RPLs), which cover from 0 to 100 percent of the MLA;
- and
- wherein a light shaping diffuser pattern is added on top of the micro-optic unit cell.
A method of making an optical element comprising a micro-optic unit cell comprised of multiple lenslets wherein the method comprises a process of randomization based on statistical uniform distribution functions of a partial or full area of the micro-optic unit cell and a process of digitally adding a pattern of a light shaping diffuser on top of the micro-optic unit cell.
