    • A method of modifying polarity of light is provided. The light propagates through a first transverse plane and has known polarization states in respective cells of the first transverse plane. A first retardation compensator having respective waveplates matching the cells then changes the polarity of the light so that light propagating through a second transverse plane is circularly polarized across the entire second transverse plane. A second retardation compensator includes a plurality of quarter waveplates that change the polarization of the circularly polarized light, so that light passing through a third transverse plane is linearly polarized. The crystal alignment of the quarter waveplates and their shape and configuration are selected so that the direction of the polarization is normal to a radius from a single point.
    • 提供了改变光的极性的方法。 光通过第一横向平面传播并且在第一横向平面的相应单元中具有已知的偏振状态。 具有与单元匹配的各个波片的第一延迟补偿器然后改变光的极性,使得通过第二横向平面传播的光在整个第二横向平面上被圆偏振。 第二延迟补偿器包括改变圆偏振光的偏振的多个四分之一波片,使得穿过第三横向平面的光线性偏振。 选择四分之一波片的晶体对准及其形状和结构,使得偏振方向垂直于单个点的半径。

    • A self-examination device including (i) a first layer formed of two sheets of material connected to form a plurality of enclosures encapsulating fluid therein and (ii) a second layer composed of a sheet of material opposing the first layer and attached to the first layer along a first portion to form a cavity between the first and second layers. The second layer is unattached to the first layer along a second portion to form an opening to the cavity to receive at least a portion of a hand to enable a person to perform a self-examination via the enclosures of the first layer.
    • 一种自检装置,包括(i)由两片材料形成的第一层,所述第一层连接以形成在其中封装流体的多个封闭体,以及(ii)由与所述第一层相对并附接到所述第一层的材料片构成的第二层 层,以在第一和第二层之间形成空腔。 第二层沿着第二部分未连接到第一层,以形成到空腔的开口以接收手的至少一部分,以使人能够经由第一层的外壳进行自我检查。
