摘 要:To obtain high-resolution three-dimensional image of laser-produced plasma, reflecting the depth of information to diagnose the uniformity of the laser-produced plasma,the method is proposed of the instantaneous multi-directional spherical crystal imaging *** multiple high-resolution spherical crystal were using in different directions,which could focus and image X-ray from the laser-prodced plasma. Secondely the imaging detector recorde the two-dimensional image of plasma on the different spherical crystal channels arranged different imaging *** three-dimensional images of laser-produced plasma was reconstructed based on the mathematical model ***-channel spectrometer was designed to diagnose the laser-produced *** the simulation experiments,the wavelength of the X-ray 0.2-20nm spectrum was obtained in laser-produced *** experiment show that the method can be applied to diagnose the three-dimensional imaging of laser-produce plasma.
