ABSTRACT
For further miniaturization of optical imaging systems, it is worth looking at some of the fascinating approaches that have been present in the tiniest creatures in nature for millions of years. The evolutionary solution of choice is found in the vision systems of invertebrates-the compound eye. Here, a large number of tiny vision systems (called ommatidia) on a curved base capture the visual information of a large field of view (FOV) in parallel at the cost of spatial resolution. Each ommatidium has a small diameter and a low information capacity when compared to the single-aperture eye. However, due to the large number of channels, a high information capacity of the overall multiaperture objective can be achieved.
