Abstract
A method for producing a holographic optical element. The method includes a step of exposing a recording material to a phase pattern which is provided by a first modulated light beam with a first phase portion. Furthermore, the method includes a step of an additional exposure of the recording material to the phase pattern, which is provided by a second modulated light beam with a second phase portion, wherein the second phase portion has a phase offset with respect to the first phase portion in order to produce a holographic optical element.

A method for producing a holographic optical element, the method comprising the following steps:
- exposing a recording material to a phase pattern which is provided by a first modulated light beam having a first phase portion;
- and
- additionally exposing the recording material to the phase pattern which is provided by a second modulated light beam having a second phase portion, wherein the second phase portion has a phase offset with respect to the first phase portion, to produce the holographic optical element.
A non-transitory machine-readable storage medium on which is stored a computer program for producing a holographic optical element, the computer program, when executed by a computer, causing the computer to perform the following steps:
- exposing a recording material to a phase pattern which is provided by a first modulated light beam having a first phase portion;
- and
- additionally exposing the recording material to the phase pattern which is provided by a second modulated light beam having a second phase portion, wherein the second phase portion has a phase offset with respect to the first phase portion, to produce the holographic optical element.
