| 摘要 |
The invention relates to a method for producing a diffraction grating (20) for a diffractive optical element having one or more subareas (22) which comprises respective grating patterns defined by a grating constant and an angular orientation. The inventive method is characterized by setting the position of at least one source (12) from which radiation is incident on the diffraction grating (20) and the position of at least one target (18) towards which the diffraction grating (20) is intended to deflect the radiation. The spatial position and orientation of the subareas (22) and the grating constant and the angular orientation of the grating patterns required to deflect the radiation incident from the source (12) on the diffraction grating (20) towards the target (18) is determined using a local vector relation which correlates the orientation of the grating in a three-dimensional space with the incident and emergent radiation and the position and orientation of the grating patterns. |
