A universal moiré effect and application in X-ray phase-contrast imaging
Abstract
Overlaying two transparent phase masks in a light beam results in a far-field achromatic intensity pattern. This effect lies at the basis of a polychromatic far-field interferometer for use in X-ray phase-contrast imaging without absorption gratings.
