Phase element for transforming beam with inhomogeneous intensity distribution to one with second inhomogeneous intensity distribution performs sequential transformations

摘要

The element transforms a beam with a distribution that is neither one-dimensional nor rotationally symmetric. The transformation of source points in the first distribution into target points in the second can be represented as a sequential implementation of a one-dimensional or rotation symmetrical transformation and a linear transformation. Independent claims are also included for the following: a mirrored element, a refractive phase element, a holographic element, an illumination device, a development method for determining the phase distribution of a phase element.
