Aberration Invariant Imaging

Aberration-invariant optical systems are combined optical/digital systems that produce near diffraction-limited images that are not affected by unknown or unmeasured lens aberrations. The unknown aberrations could be due to deterministic design errors, such as spherical aberration, while the unmeasured errors, such as chromatic aberration, could be due to low-cost fabrication procedures or large swings in ambient operating temperature. The benefit of aberration-invariant optical systems is that low-cost, low-quality opitcal systems can be modified through the addition of a special-purpose phase mask to image as a high-cost, high-quality system.
