(a) Image of an ideal 32 × 32 ± 3 gray-level Huffman-like mask. (b) Image of X-ray transmission through the fabricated mask with 20 µm pixel size, presented as P − N. (c) Histogram of graylevels in the ideal mask, image (a) (shown in orange), registered with the histogram of (b) the intensity of the X-rays transmitted through the fabricated mask (shown in blue). Both image histograms show seven closely matched peaks, representing the relative X-ray transmission intensities for mask levels −3, −2, −1, 0, +1, +2, +3. The vertical scale is counts; the horizontal axis is relative intensity.
