太赫兹探测成像技术是一种新兴的、极具发展前景的探测技术。为了满足太赫兹探测阵列的成像要求，设计了一种结构紧凑的折射型光学镜头，并采用Tracepro软件对该光学镜头轴上及离轴无穷远点在焦平面的成像情况进行了模拟仿真，优化了光学镜头结构参数。设计的光学镜头采用 HRFZ-Si 作透镜材料，并在透镜表面涂覆 parylene 抗反薄膜，其焦距为26.2 mm，视场角为16.3°，相对孔径为1.9∶1，分辨率为20 lp/mm。

Terahertz imaging technology is a rising detection technology with great development prospects. In order to satisfy the requirement for terahertz detector array imaging,a compact refractive optical lens is designed. The lens ma-terial is HRFZ-Si with a parylene anti-reflection coating on the surface. The imaging on the focal plane of the point at infinity on the axis and off axis through the optical lens is simulated by using Tracepro software,and the structural pa-rameters of the optical lens are optimized. The optimizing lens simulation results indicate that the focal length of the optical lens is 26.2mm,the filed angle is 16.3°,the relative aperture is 1.9∶1 and the resolution is 20 lp/mm.
