    摘要
  • 摘要: 研究一种基于液晶光阀的动态光学目标模拟器用视景仿真镜头，给出了视景仿真镜头的设计实例。动态光学目标模拟器由内置液晶显示系统、视景仿真镜头、外置投影仪、计算机、电缆、调整机构组成。测试设备将命令发送到计算机，计算机根据接收的指令生成模拟地形图并控制液晶光阀将图像显示出来，液晶光阀位于视景仿真镜头的焦平面位置，视景仿真镜头对液晶光阀成像后形成平行光出射，可在有限距离上产生无限远效果模拟观测结果，光学敏感器接受模拟器的出射光线并成像完成模拟试验，视景仿真镜头采用二次成像的反远结构，同时为保证与液晶光阀出射光相互匹配，采用了远心光路的结构形式。视景仿真镜头的焦距f=-22.447 1 mm，视场角是对角线视场为45，有效视场为301.5301.5；全视场畸边＜1％，在Nyquist频率42.5 lp/mm处MTF＞0.45，系统长度325 mm；视景仿真镜头与敏感器镜头配合后在敏感器像面上的照度均匀性不小于95.4％。最后给出了视景仿真镜头的测试结果。
    Abstract: A kind of visual simulation lens for dynamic optical target simulator based on liquid crystal light valve was studied and designed. The dynamic optical target simulator was composed of LCD display system, visual simulation lens, external projector, computer, cable, and adjustable mechanism. According to the instruction from the testing equipment, the simulated image of earth was generated and the liquid crystal light valve was controlled to display the simulated image of earth by computer. The liquid crystal light valve was situated on the focal plane of the visual simulation lens. Light coming from the dynamic optical target simulator was parallel light, and infinite analogue observation effect could be generated in a finite distance. The optical sensor gathered the light coming from the visual simulation lens and finished imaging simulation. Inversed telephoto structure of secondary imagery method was adopted by visual simulation lens, and in order to match the emergent light of liquid crystal light valve, telecentric beam path structure was also adopted. The focal length of the visual simulation lens was -22.447 mm, the field angle was 45,and the effective field of view was 301.5301.5. The barrel distortion of the visual simulation lens was smaller than 1%, the modulation transfer function (MTF) was greater than 0.45 at Nyquist frequency, and the length of the visual simulation lens was 325 mm. Illumination uniformity of optical sensors was better than 95.4% under the coordination between the visual simulation lens and the optical sensor. Finally the test results of the visual simulation lens were listed.
