| Zusammenfassung: | The invention relates to a holographic optical component and its use for reading or writing (plotting) heads. This use requires minimum size and low weight of the holographic optical components. According to the invention this is achieved in that a laser element and a grating structure (grid structure), integrated on a substrate and acting as holographic optics, is arranged on a large-area surface side of a flat substrate body so that a light beam of the laser element impinges directly on the grating structure and is transformed by the grating structure in such a manner that it leaves the component. |
