In this study, we discuss a new method to optimize the design of an omnidirectional gaze optical imaging system with ultrahigh resolution and long focus. An aspheric diffractive optical element is used in the optical system to offer more freedom, simplify the structure, and decrease the chromatic aberration. Owing to large image sensor arrays, the omnidirectional gaze photoelectric imaging system is capable of overcoming the shortcoming of low peripheral resolution. This has led to an increased usage of this system in military applications. Here, we describe a six-piece optical system installed on an 80 MPx full-frame CCD with 10,320 × 7752 pixels, 5.2 μm pixel size, 200° × 360° field of view, and an effective focal length of 11.6 mm. The difficulties in designing an ultrahigh-resolution fish-eye lens have been discussed and addressed. Furthermore, system performance evaluation, tolerance analysis, and image distortion calibration were also performed.

超高分辨率全向凝视光学成像系统设计

在这项研究中,我们讨论了一种优化超高分辨率和长焦距全向凝视光学成像系统设计的新方法。在光学系统中使用非球面衍射光学元件可提供更大的自由度,简化结构并降低色差。由于图像传感器阵列大,全向凝视光电成像系统能够克服外围分辨率低的缺点。这导致该系统在军事应用中的使用增加。在这里,我们将介绍安装在80 MPx全画幅CCD上的六件式光学系统,该系统具有10,320×7752像素,5.2μm像素大小,200°×360°视场,有效焦距为11.6 mm。已经讨论并解决了设计超高分辨率鱼眼镜头的困难。此外,
