【摘要】 为应对低空经济领域对高分辨率、大视场、轻量化探测的需求，提出了一种基于垂直电荷转移成像器件（Vertically charge transferring Pixel Sensors, VPS）的大视场高分辨率成像技术，该技术通过单一芯片与镜头的集成设计，利用VPS的小像元大靶面架构，在赋予系统高分辨率与大视场的同时，降低了相机的体积与质量，从而实现系统轻量化。对基于VPS技术研制的单芯片6亿像素航拍相机进行了性能验证，试验结果表明：相机的调制传递函数（Modulation Transmission Function,MTF）值在奈奎斯特采样频率714线对/毫米处接近衍射极限；系统角分辨率可达16μrad，全视场31°，无视觉可见畸变。该技术有效解决了传统光电成像技术在获取高分辨率图像时无法兼顾大视场成像与轻量化的矛盾，为未来小型无人机平台光电载荷的发展提供了新的技术思路。更多还原

【Abstract】 In order to meet the requirements of low altitude economy for high-resolution, large field of view(FOV) and lightweight detection, a large FOV and high-resolution imaging technology based on Vertically charge transferring Pixel Sensors(VPS) is proposed in this paper. This technology employs an integrated single-chip,single-lens design and a VPS architecture characterized by small pixels and a large sensor area. It simultaneously provides high resolution, large FOV, and reductions in camera volume and mass,thereby achieving system lightweighting. This study presents the development and experimental validation of a single-chip 600 million pixels aerial survey camera utilizing VPS. The experimental results show that the MTF(modulation transmission function) value of the camera is close to the diffraction limit at the cut-off frequency of 714 lp/mm; The system has an angular resolution of 16 μrad, a full field of view of 31°, and no visual distortion. This technology effectively solves the contradiction that the traditional photoelectric imaging technology can not take into account the large FOV imaging and lightweight while obtaining high-resolution images, and provides a new technical idea for the development of photoelectric load of small UAV platform in the future.更多还原
