Abstract |
AB |
[EN] A refraction at a suitably structured surface for example with an arrangement of the same between image plane and mapping optics is used to realize on the one hand a desired aliasing filtering or spatial low-pass filtering on the image plane wherein on the other hand the manufacturing of such structured surfaces may be realized in a cost-effective way. In addition to that, the plate thickness except for the amplitude of the surface structure and aspects of the stability of the plate is of no importance for handling the same, so that the integration into optical systems is facilitated. |
