We present a new coded aperture imaging technique which uses a simple large circular aperture and we apply it to imaging 20 keV X-ray emission from a laser-produced plasma. In the method known as penumbral imaging, the source casts a shadow of the aperture at the film plane. We ensure that the source is smaller than the aperture and are able to obtain high quality reconstructions of the source using deconvolution. We have achieved a resolution of about 25 μm in initial tests limited in this case by asymmetries in the coding aperture.
