Scientific paper

The addition of microchannel plate (MCP) intensification to electrography yields significant augmentations of responsivity and resolution, and furnished the ability to detect single-photon events. For low light-levels or short exposures, it remains possible to separate individual photon events from the 'film fog' with the correct algorithm, resulting in increased low light sensitivity, increased photometric accuracy, and increased resolution. Such an algorithm has been applied to MCP-intensified electrographic emulsions; attention is given to variants of the algorithm which treat the occasional overlap of photon events.
