IMPROVED CURVED MIRROR

摘要

A convex or spherical mirror is formed by securing a sheet of flexible reflective material to one side of a base sheet at least as large as the reflective surface of the mirror; the curvature of the mirror is achieved by a tensioning system secured across the other side of the base sheet; the tensioning system consists of means such as tensioning bars for curving the base about either or both of two mutually perpendicular axes in the plane of the base.
