The compound eye optical system has the characteristics of large field of view (FOV), high resolution, and strong environmental adaptability, which is an important technology that can break the mutual restraint between the field of view and spatial resolution in optical systems. Based on the characteristics of the compound eye system, we propose a multi-aperture imaging method in mid-wave infrared. The mid-wave fiber bundle array is used as a multi-aperture image plane splicing device, and the multiaperture image plane is coupled with the cooling detector using a secondary imaging structure. The experimental result shows that the optical detection system based on this technology can achieve an imaging distortion of less than 2% in arbitrary large FOV, and a uniform resolution of each large FOV angle, effectively achieving large FOV, small distortion and high-resolution imaging in mid-wave infrared imaging system.
With the increasingly prominent role of high-tech weapons in modern warfare, electronic warfare has also become a topic that has attracted worldwide attention. At present, global electronic warfare is in an important period of transformation and development. In particular, the US military has made substantial progress in electronic warfare in recent years. The development of electronic defense has played a decisive role in future wars. This article introduces the application system architecture and operating mechanism of SDM. At the same time, it introduces the application of plug-and-play SDM software in modern electronic defense system operations, and expounds the role of intelligent command in future electronic warfare. SDM software can realize the plug-and-play of sensor equipment, and it plays a key role in the intelligent network of electronic defense.
