    • Headgear apparatus allows a viewer to see objects in a periscopic direction and a normal direction simultaneously. A periscope is mounted to a headpiece that is easily supported by the viewers head. The periscope has movable mirrors and an extending periscope section to allow the viewer to change the angle of the periscopic view relative to a plane containing a normal line of sight and the peripheral distance of the periscopic view, respectively. The apparatus further has a sectional periscope, whereby sections containing the reflective elements of the periscope can be rotated relative to each other and change the periscopic view in the plane of the forward line of sight. The head gear apparatus is adapted to a mask or an underwater mask that allows a viewer to see objects in a periscopic direction and a forward direction in diverse environments such as under water.
    • 头饰设备允许观看者同时观看偏光方向和法线方向的物体。 潜望镜安装在容易被观察者头部支撑的头饰上。 潜望镜具有可移动镜和延伸的潜望镜部分,以允许观看者相对于包含法线视线的平面和透视视图的周边距离改变透视图的角度。 该装置还具有截面潜望镜,由此包含潜望镜的反射元件的部分可以相对于彼此旋转并改变在前视线的平面中的透视图。 头盔装置适用于允许观察者在诸如水下的各种环境中观察物体在偏光方向和向前方向上的掩模或水下掩模。
