我们提出了一种新的编码孔径成像技术,它使用一个简单的大圆孔,并将其应用于激光产生的等离子体的20keV X射线辐射成像。在被称为半影成像的方法中,光源将光圈的阴影投射在胶片平面上。我们确保声源小于孔径,并且能够使用反卷积获得高质量的声源重建。在最初的测试中,我们已经达到了大约25μm的分辨率,在这种情况下,受到编码孔径不对称的限制。
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.
