X-ray phase contrast imaging and noise evaluation using a single phase grating interferometer

Opt Express. 2013 Jul 15;21(14):17340-51. doi: 10.1364/OE.21.017340.

Abstract

In this paper we present some quantitative measurements of X-ray phase contrast images and noise evaluation obtained with a recent grating based X-ray phase contrast interferometer. This device is built using a single phase grating and a large broadband X-ray source. It was calibrated using a reference sample and finally used to perform measurements of a biological fossil: a mosquito trapped in amber. As phase images, noise was evaluated from the measured interferograms.
