中文摘要：
针对以金属铝作反射介质的铁电液晶光寻址空间光调制器，提出了一类光-光等效电路模型，达到拓展电路模型到调制器光电响应特性研究的目的．擦除光对光电响应特性影响的模拟结果表明，擦除光能极大加快信息的擦除速度，帧速2．2kHz，写入光强10mW／cm^2时，取擦除光强为10mW／cm^2，恰能将信息擦除．擦除光能有效抑制调制器的非期望输出光功率和调节器件的光电响应速度；对应于无擦除光注入的情况，注入1mW／cm^2擦出光使非期望输出光功率下降77％，响应速度减慢9％．通过设计肖特基势垒高度，擦除光可实现对读出光的开关和灰度调制等功能．给出了实现灰度调制功能的实例．由该模型得到的仿真实验结果在趋势与量级上均与有关文献的实测结果一致．
英文摘要：
To enlarge the application of circuit into studying modulator,an equivalant circuit model is presented, which is b modulator erase-light incorporating ferroelectric liquid crystals and using opto-electric responses of the spatial light ased on the optically addressed spatial light metal A1 as the reflector. And the effect of on opto-electric responses is studied. The simulation results indicate that the informati erasing velocity is quickened frame speed is 2.2 kHz and by injecting erase-light,the critical erase-light intensity is 10 mW/cm^2 w write-light intensity is 10 mW/cm^2. Also injecting erase-light can effectively restrain the unexpected output-light power and adjust the response velocity. Comparing to the case of null erase-light,injecting 1 mW/cm^2 erase-light decreases the unexpected output-light power by 77 % and slows down the response velocity by 9 %. Erase-light can be used in switching and gray-scale modulation if the height of Schottky barrier is well-designed,and an example of gray-scale modulation realized by erase-light is given. And the simulation results from the model have shown good agreement with the reported experimental results in both magnitude and tendency.
