作者研制了一种具有高分辨率成像能力的自触发像增强管。由作为具有100 mm光电阴极直径的静电透镜的第一图像增强管检测的图像被半反射镜分离成用于CCD读出（768×494像素）和快速控制的路径，以识别和触发图像。该系统具有高信噪比和207 ~ 240 μm的空间分辨率，可用于高能物理和天体物理实验以及高速摄影。当与作者提出的1角分分辨率50°视场光学系统相结合时，利用该装置进行超高能宇宙线和高能中微子的观测，有望在粒子天体物理学领域取得革命性的进展，作为传统天文学多波长观测的补充技术。
The authors have developed a self-triggered image intensifier tube with high-resolution imaging capability. An image detected by a first image intensifier tube as an electrostatic lens with a photocathode diameter of 100 mm is separated by a half-mirror into a path for CCD readout (768×494 pixels) and a fast control to recognize and trigger the image. The proposed system provides both a high signal-to-noise ratio to improve single photoelectron detection and excellent spatial resolution between 207 and 240 μm rendering this device a potentially essential tool for high-energy physics and astrophysics experiments, as well as high-speed photography. When combined with a 1-arcmin resolution optical system with 50° field-of-view proposed by the present authors, the observation of ultra high-energy cosmic rays and high-energy neutrinos using this device is expected, leading to revolutionary progress in particle astrophysics as a complementary technique to traditional astronomical observations at multiple wavelengths.
