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.
在本文中，我们展示了一些利用最近基于光栅的X射线相衬干涉仪获得的X射线相衬图像的定量测量结果和噪声评估。该装置使用单个相位光栅和大型宽带X射线源构建而成。它通过一个参考样品进行校准，最终用于对一个生物化石——一只被困在琥珀中的蚊子进行测量。作为相衬图像，噪声是从测量得到的干涉图中评估出来的。
