| 摘要: |
| 薄膜晶体管液晶显示器TFT-LCD(Thin-Film-Transistor Liquid Crystal Device)是信息光学研究中一种非常重要的电寻址空间光调制器SLM(Spatial Light Modulator)。实验中通过调整TFT-LCD的起偏器或检偏器的方向，可以分别得到正像、边缘暗突出像、负像等，并结合具有双折射特性的线性扭曲液晶介质对线偏振光的调制理论，对此给出解释。 |

| Abstract: |
| TFT-LCD is a very important spatial light modulator in the optical information processing. The positive optical image,the edge weakened optical image and the negative optical image are obtained by changing the direction of the polarizer or analyzer when the spatial light is modulated by TFT-LCD with the digital images inputed. It is explained in accordance with the theory of the linear-twisted liquid crystal device as an spatial optical complex amplitude modulator. |
