摘　　要：广角透镜技术采用透镜代替传统的反射镜,可以有效实现兼顾大视场、高角分辨、高能量分辨等优点,是测探时变源和GRBs等产生高能宇宙线辐射最理想的手段之一。文章介绍广角透镜技术原理,并简要分析广角透镜优缺点。在此基础上,对采用广角透镜技术进行宇宙射线探测的GAW实验、JEM-EUSO实验和西藏大学水透镜实验进展做介绍。Wide-angle lens technology uses lens instead of traditional mirror, which can effectively take into account the advantages of large field of view, high angle resolution and high-energy resolution. It is one of the most ideal means to detect time-varying sources and GRBs to produce high-energy cosmic ray radiation. In this paper, the technical principle of wide-angle lens is introduced, and the advantages and disadvantages of wide-angle lens are briefly analyzed. On this basis,the progress of GAW experiment, JEM-EUSO experiment and water lens experiment of cosmic ray detection using wide-angle lens technology are introduced.
