Abstract
This project investigates the fundamental imaging capability of an optic with a physical
thickness substantially less than 1 mm. The analysis assumes that post-processing can overcome
certain restrictions such as detector pixel size and image degradation due to aberrations. A first
order optical analysis quickly reveals the limitations of even an ideal thin lens to provide
sufficient image resolution and provides the justification for pursuing an annular design. Some
straightforward examples clearly show the potential of this approach. The tradeoffs associated
with annular designs, specifically field of view limitations and reduced mid-level spatial
frequencies, are discussed and their impact on the imaging performance evaluated using several
imaging examples. Additionally, issues such as detector acceptance angle and the need to
balance aberrations with resolution are included in the analysis. With these restrictions, the final
results present an excellent approximation of the expected performance of the lens designs
presented.3
