| 英文摘要 | A holographic weapon sight has a housing with a viewing end and an opposing target end, a viewing path being defined from the viewing end to the target end. A light source energized by a power source projects a light beam along a path onto a liquid crystal cell module. A power controller in communication with the power source is operable to adjust the brightness of the light beam from the light source. The liquid crystal cell module is operable to rotate and polarize the light beam to further adjust the brightness of the light beam. The light beam from the liquid crystal cell module illuminates a holographic optical element (HOE) that reconstructs an image of a reticle. |
