Paper Abstract

Low-light-level image intensifier images weak optical signal through electron multiplication process in Low-light-level night vision device, the key technology of intensifier is electron multiplier, the thesis put forward three kinds of electron multiplication methods. One is that the electron multiplier device is the avalanche transistor made use of the semiconductor material, the thesis analyses the photoelectric conversion theory and rapid multiplication avalanche breakdown conditions with PN junction of the avalanche diode under reverse bias by light excitation; the second approach is to use gas discharge theory to explains the electron multiplication process in the low-pressure gas and high-pressure gas discharging breakdown by photon excitation; the third method is photoelectron multiplication gain theory,in the microchannel plate (MCP) as the second generation image intensifier in vacuum condition and the applied voltage. The thesis analyses that the electronic gain efficiency is better than the other two methods ,and proposes the avalanche transistor can be key device of image intensifier.
