摘要

在现代机载光电探测设备中,旋转折射光楔对起着扩大探测视场和搜索范围的重要作用.首先基于几何光学和光的标量衍射理论对旋转折射光楔对的折光特性进行了数学分析；然后结合其在机载光电探测设备中的功能要求,研究了一种旋转光楔对控制模型,并基于该控制模型设计了旋转折射光楔对的控制算法；最后,通过仿真实验证明了该控制算法的正确性和可靠性.%In airborne photoelectronic detection equipment, rotary dual-wedge prism system plays an important role for enlarging the detection scope and searching range. First, the refractive property of the dual-wedge prism system was analyzed according to the theories of geometrical optics and scalar diffraction. Then, a control model was established for the dual-wedge prism system considering the functional requirements of it in airborne photoelectronic equipment, and the control algorithms were given based on the model. The correctness and reliability of the control model and control algorithms were proved through simulation.
