In this paper, a high spatial resolution, high gating speed framing camera capable of four separate two-dimensional images is designed and tested. A mirror-based image splitter has been designed and developed to provide a separate image for each arm with equal path length and equal intensity splitting while having a spectral flat response. Fast gating of a single frame is accomplished by using a proximity-focused microchannle-plate image-intensifier (MCPII) gated by a MOSFET-based pulse module with adjustable gate width from 3 ns to D.C. operation. Multiple frames are obtained by using multiple gated tubes with time intervals between consecutive frames can be adjusted flexibly. Its spatial resolution reaches 36.5 lp/mm with each frame having a 4.6-ns gate width. Furthermore, a three-dimensional MCPII model is developed to investigate the transit time and spatial resolution of the proximity-focused MCPII based on the Finite Integral Technique (FIT) and Monte Carlo method (M–C method).

本文设计并测试了一种高空间分辨率、高选通速度的分幅相机，能够拍摄四个独立的二维图像。已经设计和开发了一种基于镜像的图像分离器，为每个臂提供具有相等路径长度和相等强度分离的单独图像，同时具有光谱平坦响应。单帧的快速门控是通过使用接近聚焦微通道板图像增强器 (MCPII) 来实现的，该图像增强器由基于 MOSFET 的脉冲模块门控，具有从 3 ns 到 DC 操作的可调门控宽度。通过使用多个门控管获得多帧，连续帧之间的时间间隔可以灵活调整。它的空间分辨率达到 36.5 lp/mm，每帧具有 4.6 ns 的门宽。此外，
