Abstract

To achieve a further extension of the depth of field in wavefront-coded imaging by reducing the impact of focus error in the optical transfer function, we propose the use of a free-form phase mask (FPM) instead of a conventional cubic phase mask (CFM). We optimized the shape of the FPM using the simulated annealing algorithm and confirmed that the optimized FFM provides a much larger focal tolerance and better final images than the CPM in the noise-free case.
