title = "Contrast enhancement of luminescence images via point-spread deconvolution",
abstract = "We investigate the impact of point-spread in the silicon CCD sensor of a BT Imaging LIS-R1 luminescence imaging system. It is found that an experimental definition of the point-spread function allows for a significant restoration of CCD point-spread to be achieved. A comparison with short-pass filtering is performed, demonstrating that point-spread will still have a measurable influence on image quality while reducing the luminescence signal and increasing the relative noise level. An implementation of point-spread deconvolution is presented at a multi-crystalline silicon grain boundary, illustrating a practical enhancement of resolution in a typical high-contrast scenario. The characteristics of the point-spread presented here are specific to the experimental apparatus investigated, but the procedure described is universally applicable.",
