The effect of the form of the illuminating wave on array
illuminators is investigated. Attention is focused on spherical
illumination, and relevant parameters such as spot size and compression
ratio are discussed. In addition, a general approach is presented
to designing a Talbot array illuminator that operates under spherical
illumination. It is shown how spherical illumination can be used as
a degree of freedom, and an example of application in the field of
human eye aberration correction is given.
