A set of non-configurable transversely-displaced masks has been designed and fabricated to generate high-quality X-ray illumination patterns for use in imaging techniques such as ghost imaging (GI), ghost projection, and speckle tracking. The designs include a range of random binary and orthogonal patterns, fabricated through a combination of photolithography and gold electroplating techniques. We experimentally demonstrated that a single wafer can be used as an illumination mask for GI, employing individual illumination patterns and also a mixture of patterns, using a laboratory X-ray source. The quality of the reconstructed X-ray ghost images has been characterized and evaluated through a range of metrics.
已设计并制造出一组不可配置的横向位移掩模，以生成高质量的X射线照明图案，用于诸如鬼成像（GI）、鬼投影和散斑跟踪等成像技术。这些设计包括一系列随机二进制和正交图案，通过光刻和金电镀技术相结合制造而成。我们通过实验证明，使用实验室X射线源，单个晶圆可用作GI的照明掩模，采用单独的照明图案以及图案的混合。已通过一系列指标对重建的X射线鬼图像的质量进行了表征和评估。
