In this contribution we describe some approaches which attempt to increase the resolution of optical imaging systems. In particular, we are interested in scanning systems, such as the confocal microscope, using both coherent and fluorescent light, an

This work analyzes the performance of the coded-aperture based x-ray phase contrast imaging approach, showing that it can be used at high x-ray energies with acceptable exposure times. Due to limitations in the used source, we show images acquired at

A novel technique based on coded apertures which makes x-ray phase contrast imaging (XPCi) feasible with conventional sources has been recently developed at University College London. This technique is expected to enable for the first time real-world

Image smear caused by frame transfer in CCD detectors is considered in terms of an image restoration problem, and an efficient method of achieving smear removal is described and demonstrated. A frequency analysis of the image smearing process identif
