摘　　要：微通道板(Microchannel Plates,MCP)是一种先进的电子倍增器件,在微光夜视等多个领域有着广泛的应用。传统铅硅酸盐玻璃微通道板(Lead Silicate Glass Microchannel Plates,LSG-MCP)越来越不能满足小孔径、高分辨率、环境友好等方面的要求,寻求替代产品成为研究热点。详细介绍了一种新型微通道板——阳极氧化铝微通道板(Anodic Aluminum Oxide Microchannel Plates,AAO-MCP)的研究进展,包括多孔AAO的特点、微通道的形成、功能层的制备、计算机模拟等。AAO-MCP具有孔径小、面积大、耐强磁场、工作温度范围宽等特点,应用前景广阔。最后分析了AAO-MCP存在的问题以及未来发展方向。Microchannel plates （MCP） are advanced electron multiplier devices, which are widely used in low-light-level night vision and other fields. The traditional lead silicate glass microchannel plates （LSG-MCP） are increasingly unable to meet the requirements of small diameter, high resolution and environment-friendness, so it is necessary to find some novel alternative materials and technology, such as anodic aluminum oxide microchannel plates （AAO-MCP）. This paper describes the research progress of the AAO-MCP in details, including the characteristics of the porous AAO, the forming of microchannel, functional film preparation and computer simulation. AAO-MCP has some advantages, such as smaller channel diameter, large area, low sensitivity to strong magnetic field, and wide operating temperature range. Finally, the most difficult problems in AAO-MCP and the development in the future are presented.
