Progress in lithography and nanofabrication [E. Di Fabrizio et al., Nature (London) 401, 895 (1999)] has made it possible to apply differential interference contrast (DIC) in x-ray microscopy using an original x-ray doublet lens based on two specially developed zone plates. Switching from bright-field imaging (absorption contrast) to x-ray DIC, we observe, similar to visible-light microscopy, a dramatic increase in image contrast for weak absorbing samples. We anticipate that this technique will have a significant impact on x-ray imaging and may play a role comparable to DIC imaging in visible-light microscopy.
