Multiframing Mach-Zehnder interferometer for spatiotemporal plasma density measurement in “Dragon-1” target zone

Interferometric measurement is used to establish the spatially and temporally resolved plasma density distribution. The Mach-Zehnder interferometer is established in “Dragon-1” 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 on the order of 10
