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.
