A proximity-focused image intensifier, fiber optically coupled to a charge-coupled device, forms a compact and adaptable detector system, an ICCD, that is useful over an extraordinarily wide range of input intensities. For critical photometric applications, persistence in the glowfrom the phosphor of the image intensifier must be taken into account. A model of persistence can help in understanding the capabilities and limitations of the detector and in designing experiments using it. The model can also be used to derive photometric correctionsfor persistence. The necessityfor photometric corrections for persistence can often be avoided by careful experimental design.
