在一个方面中,本发明涉及一种用于照明、检测和/或全息表示的光导结构,包括用于引导至少第一光谱的电磁辐射的至少一个平面光导、位于所述光导的第一侧面上的至少一个照明装置以及用于出射耦合在所述光导结构中引导的电磁辐射的至少一个全息出射耦合结构。由所述照明装置辐射入的光可以具有大的角度范围,所述全息出射耦合结构具有小的角度范围。本发明还涉及一种用于这样的光导结构的生产方法和一种包括光导结构的操作元件。

    In one aspect, the invention relates to a lightguide structure for illumination, detection and/or holographic representation, comprising at least one planar lightguide for guiding electromagnetic radiation of at least a first spectrum, at least one illumination arrangement located on the first side face of the lightguide, and at least one holographic outcoupling structure for coupling out electromagnetic radiation guided in the lightguide structure. The light radiated in by the illumination arrangement can have a large angular range, the holographic outcoupling structure having a small angular range. The invention also relates to a production method for such a lightguide structure and to an operating element comprising a lightguide structure.
