为解决传统的光栅直透镜在红外模拟干扰环境下敏感和成像效果不好的问题，设计了一种改进的红外模拟干扰环境下超广角波导光栅直透镜，利用单自由曲面的折光能力实现光线准直出射，构建固定目标面均匀照明微分方程，采用切面迭代法求解单个自由曲面上的点坐标，根据能量守恒确定光源发光角，进行双自由曲面均匀准直照明，分析各接收面上的照度分布和光斑尺寸，在红外模拟干扰环境下，根据点到线模型中成像空间，构建红外模拟干扰下的超广角透镜模型，提高可透镜在红外模拟干扰环境下的成像能力和透射能力。仿真结果表明，该设计方案满足红外成像准线性区域范围要求，成像的像素保真度较好，克服了光学敏感性能，改进了成像效果，性能优越。

In order to solve the traditional grating straight lens in the simulated infrared interference environment sensitivity and imaging effect is not good, the design of a simulated infrared jamming environment improved under ultra wide wave?guide grating to achieve direct lens, collimating light emitted by single free surface refractive power, building a fixed target uniform illumination differential equation using the coordinate free surface, single section iterative method for solving the point, according to the energy conservation to determine the light emitting angle, two freedom surfaces uniform collimated il?lumination, illuminance distribution and analysis of spot size of each receiving surface, in the simulation of infrared jam?ming environment, according to the point to the imaging space line model, the construction of ultra wide angle lens model of infrared simulation of jamming, improve the lens in the simulated infrared interference environment imaging ability and transmission ability. The simulation results show that, the design scheme can meet the requirements of imaging infrared quasi linear regions, pixel imaging better fidelity, to overcome the optical sensitivity, improved imaging effect, it has superi?or performance.
