    • An optical sensing device is suitable for detecting information on an information plane. The optical sensing device includes a light source, an optical grating and an optical detector. The light source is suitable for providing a light beam along a first axis. The light beam is illuminated on the information plane and is converted into an optical signal exiting the information plane. The optical grating has at least a split. The optical detector is suitable for receiving the optical signal to generate the information. The optical signal passes through the split of the grating and reaches the optical detector along a second axis that is positioned at an angle with respect to the first axis.
    • 光学感测装置适用于检测信息平面上的信息。 光学感测装置包括光源,光栅和光学检测器。 光源适于沿着第一轴提供光束。 光束在信息平面上被照亮,并被转换成离开信息平面的光信号。 光栅至少有一个分裂。 光学检测器适用于接收光信号以产生信息。 光信号通过光栅的分割并沿着相对于第一轴线成一定角度的第二轴线到达光学检测器。
