The invention relates to a contact lens for a head-mounted display, HMD, comprising a lens body configured for application to the surface of a contact lens wearer's eye, wherein the lens body has a central optically transparent region, wherein the optically transparent region is composed of a plurality of concentric rings of increasing diameter, wherein in the radial direction each concentric ring is configured either as a Fresnel zone or as a simple lens portion, wherein Fresnel zones and simple lens portions alternate with one another, wherein the Fresnel zones are configured for sharp retinal imaging of image data presented at a fixed distance in front of the surface of the eye, wherein the simple lens portions are configured for sharp retinal imaging of the distance and near vision zones of the contact lens wearer. The invention further relates to an HMD, in which a contact lens according to the invention is used for visualization of variable image data presented in a display at a fixed distance in front of the surface of the eye.

Contact lens for use with an HMD and associated HMD

Described is an arrangement for the transformation of laser radiation. A projection system for generating spatially modulated laser radiation includes an optical arrangement for transforming laser radiation, a field lens, a spatial light modulator and a projection arrangement. By means of the optical arrangement, incidental laser radiation in a first direction (E) is reflected on an aspherically curved, reflective surface in a second direction (R), where in a plane perpendicular to the first direction (E) the laser radiation has an inhomogeneous beam profile (GB, G) with a first beam axis (A) and a second beams axis (B) perpendicular to the latter, and the aspherical curvature is designed, during the reflection on the reflective surface, to transform the inhomogeneous beam profile of the laser radiation for the first beam axis (A) and/or the second beam axis (B) respectively into a homogenous top-hat beam profile (H).
