METHOD FOR PRODUCING A HOLOGRAPHIC OPTICAL ELEMENT (HOE), WHICH IS PROVIDED FOR PROJECTION IN A PROJECTION SYSTEM, A HOLOGRAPHIC OPTICAL ELEMENT OF THIS KIND, PROJECTION DEVICE, LENS FOR DATA GLASSES AND DATA GLASSES OF THIS KIND

摘要

The invention relates to a method (100) for producing a holographic optical element (HOE) (210), which is provided in a projection system for projection. According to the method (100), a hologram (210) is recorded by causing a first Gaussian beam (212) and a second Gaussian beam (214) for at least two different configurations to interfere on a holographic film (200). The first Gaussian beam (212) is a reference beam, which, for the at least two different configurations, is identical to a reconstruction beam with which the HOE (210) is reconstructed. Furthermore, the second Gaussian beam (214) is an object beam, which, during the reconstruction of the HOE (210) using the reconstruction beam, is identical to a projection beam which is used in the projection system for projection. For the at least two different configurations for the second Gaussian beam (214), at least one beam property is specified, which depends in each case on specified projection properties of the projection system.
