To prepare a new diagnostic tool for the laser-imploded plasma, we have developed a time-resolved, two-dimensional monochromatic imaging system that consists of a pinhole array, a flat diffraction crystal, and an x-ray streak camera without cathode slit. We have successfully reconstructed time-resolved two-dimensional images of an Ar resonance line emitted from an imploded plastic shell filled with D{sub 2}/Ar mixture gas. The current system provides the temporal resolution of {approximately}24 ps and the spatial resolution of {approximately}16 {mu}m for the direction perpendicular to the spectral dispersion. The spatial resolution parallel to the spectral dispersion is {le}27 {mu}m, that depends on the crystal broadening and the spectral linewidth. {copyright} {ital 1997 American Institute of Physics.}
