基于核动力船舶反应堆舱的具体应用需求，研制了一款无源、小型化、模块化，具有良好耐高温和耐辐照特性的视频采集装置。它利用光纤阵列成像技术和基于稀疏表示的图像超分辨率重建算法来获取高质量的图像。通过主观质量评分法，将该装置与传统的电子摄像管摄像机、CCD/CMOS彩色/黑白摄像机进行一系列的耐高温、耐辐照的实验对比分析。不同环境下的实验结果表明，该视频采集工作稳定可靠，完全满足设计要求。另外，该装置还具有良好的泛化推广能力，稍加适应性设计，即可应用于其他类似的环境中。
According to the specific requirements in reactor room of nuclear power ship, a passive video acquisition device is developed based on optical fiber imaging technology and sparse super-resolution reconstruction model. It features small size, modular design, high-temperature resistance and strong radiation resistance. Based on Mean Opinion Score, adaptive capacity to high-temperature and strong radiation is well studied by comparison with TV camera, CCD/CMOS color/BW cameras. It is proved by experiments in different environments that this device can work well and completely meet design requirements. Additionally, this device is of good generalization ability and widely used in similar applications after adaptive design.
