Paper Abstract

A specially designed-Proximity-focused-MCP-Image Intensifier (MCP-II) has been widely used for a high speed diagnosis system as a ns-level-electronic shutter. Its temporal-spatial (dynamic) MTF or resolution are much concerned in the engineering for single exposure conditions of various shutter times, and input illuminations as well. On basis of the theory of Fourier spectrum and signal-to-noise, it has been analyzed in present paper that dynamic-MTF (or resolution) of the MCP-II system is always deteriorated by its limited temporal frequency bandwidth, as well as S/N performance. Several expressions are given to relate the device's dynamic MTF (or resolution) to its static MTF, input illumination and S/N performances. The theoretical analysis is very useful in evaluating and designing some high speed diagnosis systems with a proximity-focused-image intensifier as a electronic shutter.
