Abstract
An alignment method for controlling a mirror (100) makes it possible to orient an optical compensation digital hologram (3) relative to a mirror control tool. The control tool is designed to light up, one by one, confined portions (S10) of a reflecting surface (S100) of the mirror, and the entire surface is controlled while moving a lighting and image capture assembly (20), between a series of views, over the mirror. The control tool can then be of small size, even when the mirror has a very low curvature and a large size.
