Pseudo-random prism arrays for lensless computational imagers

Birch, Gabriel C.; Woo, Bryana L.; Dagel, Amber L.; LaCasse, Charles F.

We report on the design of a refracting prism array for use in a computational lensless imaging system. The technique discussed enables creation of a refracting element that maximizes signal on a detector region. Examples of pseudo-random prism arrays for the generation of images are provided. The pseudo-random prism array is compared to a randomly oriented prism array and the advantages of the optimal scattering element are highlighted.
