High-bandwidth large-angle fast reflecting mirror based on integrated reflecting mirror

The invention relates to the field of fast control reflectors, and aims to reduce the mass of the reflector by embedding a flexible support hinge part in the back surface of the reflector and canceling the arrangement of a reflector support. The high-bandwidth large-angle fast reflecting mirror comprises the integrated reflecting mirror, a flexible supporting hinge and a base, a first mounting groove is formed in the center of the back face of the integrated reflecting mirror, and the end, facing the integrated reflecting mirror, of the flexible supporting hinge is connected with the bottom of the first mounting groove; the flexible supporting hinge is closer to the mirror surface of the integrated reflecting mirror, and the flexible supporting hinge is arranged on the base. According to the invention, the flexible support hinge is partially embedded in the back surface of the reflector and is provided with the flexible support hinge mounting groove, so that the flexible support hinge is closer to the mirror
