Abstract
Systems and methods are described for extending the dynamic range of imaging systems, and more particularly fluorescence or luminescence imaging systems, having low optical background and a linear detector response. Images of a sample at each of a set of exposure times are acquired, a system-level dark estimate for each exposure time is subtracted from each image to form dark-corrected images, and the different exposures (dark-corrected images) are merged into a wider dynamic-range image. Typically merging is performed on a pixel-by pixel basis.
