METHOD AND DEVICE FOR OBTAINING REPRESENTATION OF THE REAL SURFACE OF AN ASPHERIC, SPHERICAL OR PLANAR MIRROR IN PARTICULAR FOR CONTROLLING CERTAIN OPTICAL PARAMETERS OF THIS MIRROR.

摘要

The invention relates to a method and a device for obtaining a representation of the real surface of a mirror. BR/ This surface is represented by a set of values which correspond to the radial or approximately radial distances which separate points distributed on the surface of the mirror from a spherical reference surface. To implement this method, a device is used which comprises a support (1) provided with at least three stops (2) able to support the support and distributed or able to be distributed as points on the surface of a sphere said support further carrying at least one distance sensor (3). BR/ The invention applies in particular to the control of the optical parameters of an aspheric, spherical or plane mirror and, in particular, to the telescope mirrors. / P
