| 摘要 |
The invention concerns a polarization converting system (100) and a method for adjusting same comprising an array (110) of polarizing beam splitters and at least one first lens (115) and a second lens (120) in cascade for receiving non-polarized light produced by a light source (135). The position of the first and second lenses can be set to adjust the non-polarized light focus on the polarizing beam splitter array. The polarization converting system may be incorporated in a liquid crystal display which includes an imaging device (155). A third lens (125) and a fourth lens (130) may be arranged in cascade to receive the polarized light from the polarizing beam splitter array and focus the polarized light on an imaging device. The system can be adjusted by setting the position of at least one of the lenses to focus the non-polarized light on the polarizing beam splitter array, thereby reducing reflection.
