The high-time-resolution streak photographic system equipped with a powder gun and a two-stage light gas gun has been constructed for the Hugoniot measurement of solids at pressures up to ${>}300$ GPa. For this system, a compact rotating-mirror-type streak camera and a long-pulsed dye laser with no Q-switch were produced. A time resolution higher than 1 ns was achieved by using a 2-μm-wide slit of the camera formed using the laser. The shock velocity and particle velocity of steady shock waves of the materials with a shock velocity of ${\sim}6$ km/s can be measured by the inclined-mirror method with the basic errors of 0.2 and 0.1–0.2%, and 0.2 and 0.35–0.45% for symmetrical and asymmetrical impact, respectively, depending on shock velocity and impact velocity.
