X-ray ghost imaging of a circuit board. (a) Projection image with a size of 880 × 330 pixels; (b) GI reconstruction using the ensemble averaging algorithm, where the bucket size for SAXGI is 110 × 110 pixels and the number of measurements is M = 11234; (c) GI reconstruction using the compressed sensing algorithm, with the same bucket size and measurement number; normalized line profiles for weak absorption (d) and strong absorption (e) circuit components at positions denoted by red and blue lines in (a) and (c), respectively. |
