Variable-included-angle plane mirror radiation and contraction dynamic imaging experiment instrument

The invention discloses a variable-included-angle plane mirror radiation and contraction dynamic imaging experiment instrument. The instrument is mainly composed of a horizontal flat plate, a centralgroove, an illuminating lamp, an automatic vortex ring former, a vortex ring, plane mirrors, an elastic belt, hinges, a graphometer and an observation hole, and is characterized in that the two equal-size long-strip-shaped plane mirrors are fixed on the two movable hinges respectively; the elastic belt can control the included angle between the two plane mirrors and the overall positions of the two plane mirrors in space; the extension line of the vertical intersection line of the graphometer is fixed on the horizontal flat plate; the automatic vortex ring former is fixed on the horizontal flat plate; the movement direction of the vortex ring in the automatic vortex ring former is on the extension surface of the bisecting surface of the included angle between the two long-strip-shaped plane mirrors; and the illumi
