Images recorded by the 3 × 6 arrayed CCD X-ray detector with a grid mask which was placed in front of the detector. (a) Raw data and (b) with image distortion correction. Flood-field irradiation of the visible light was obtained with a light diffuser made of paper. The exposure time was 100 s and the detector gain setting of the detector was 4.05 e− ADU−1 (low gain). |
