Imaging with the Compact Light Source (video) Lyncean Technologies, Inc. Loading video... Caption Differential Phase Contrast Imaging naturally produces three images by analyzing the fringe intensity for each pixel as the second grating of the interferometer is scanned. The average is just the normal X-ray absorption image, the depth of the fringe oscillation yields the dark field image and the phase of the fringe oscillation yields the phase image. The video shows first a bee and then a moth from the recently published paper. The first absorption image fades to the dark field image which then fades to the phase image. Notice that the dark field image is sensitive to the insect's fiber support structure while the phase image is sensitive to the filaments supporting the insect. The data was recorded on a CCD detector on loan from Rayonix which has 80 micron pixel size.
