    • An optical sensing head, which is for reading out an optical data memory, has a substrate with a main surface. An edge-emitting laser component is configured on the main surface of the substrate and has irradiation axis oriented essentially parallel to the first main plane. A deflection device is arranged on the main surface of the substrate and deflects the laser radiation in a direction that is essentially perpendicular to the main surface. At least one signal detector is provided for sensing the laser radiation that is reflected by the optical data memory. An optical element guides the deflected laser radiation to the optical data memory and guides reflected laser radiation to the signal detector. The optical element is connected to the substrate by at least one supporting element. The invention also includes a method for fabricating such a sensing head.
    • 用于读出光学数据存储器的光学检测头具有具有主表面的基板。 边缘发射激光器部件被构造在基板的主表面上,并具有基本上平行于第一主平面定向的照射轴。 偏转装置设置在基板的主表面上,并使激光辐射沿基本垂直于主表面的方向偏转。 提供至少一个信号检测器用于感测由光学数据存储器反射的激光辐射。 光学元件将偏转的激光辐射引导到光学数据存储器并将反射的激光辐射引导到信号检测器。 光学元件通过至少一个支撑元件连接到基板。 本发明还包括一种用于制造这种感测头的方法。
