Parabolic rotating surface array integrating mirror and design method thereof

The invention discloses a parabolic rotating surface array integrating mirror and a design method thereof. A reflecting surface of the integrating mirror is formed by alternately arranging a series ofconcave parabolic rotating surfaces and convex parabolic rotating surfaces, and curvature continuity is kept between the rotating surfaces. Each parabolic rotating surface reflects incident light toa focusing light spot to form light spots with the same size and shape. Incident light with non-uniform light intensity distribution is divided, reflected and superposed to a focusing light spot by aseries of parabolic rotating surfaces to form the focusing light spot with regular shape and uniform light intensity distribution. According to the parabolic rotating surface array integrating mirrorprovided by the invention, incident light with non-uniform light intensity distribution can be converted into focusing light spots with sharp boundaries and uniform light intensity. The parabolic rotating surface array integrati
