Mach–Zehnder Interferometer for Spatiotemporal Plasma-Density Measurement in “Dragon-I” Target Zone

In this paper, interferometric measurement is used to establish the spatial- and temporal-resolved plasma-density distribution. The Mach-Zehnder interferometer is established in "Dragon-I" target zone; the experiment with the interferometer was conducted, and interferograms were obtained by the high-speed multiframe CCD camera. By counting the fringe shift on the interferograms, the density of plasma was calculated to be at the order of 10
