Figure 4
Detector images of the (a) positive (P) and (b) negative (N) 15 × 15 pixel Huffman-like mask generated using 3 × 3 binary pixels of pitch 15 µm. (c) The signed mask, re-generated as PN. (d) Histogram of image (c). The three peaks show the distribution of the measured X-ray illumination intensities that passed through the −1, 0, +1 sections of the fabricated mask, respectively. The vertical axis in (d) is counts; the horizontal axis displays the relative signal intensity.
