ABSTRACT:
The invention relates to an appliance for measuring or controlling an optical element (3) comprising illumination means (1) and an associated artificial vision system (2), in which the optical element (3) can be inserted between the illumination means (1) and the artificial vision system (2), said illumination means (1) comprising programmable optoelectronic means for producing a luminous background with spatially and temporally variable brightness. The inventive appliance is characterised in that the programmable optoelectronic means are embodied in such a way as to consecutively generate a plurality of mires, each comprising a pattern which is repeated in a contrasted manner on a uniform background with a high spatial frequency of between 0.01 and 100 patterns/mm, or such that two adjacent patterns are separated by an angle between 0.1 and 30 degrees, said angle being measured from the point of the object on which the pattern is observed. Said generated mires are consecutively spatially staggered in such a way that a plurality of images corresponding to the mires is captured by the artificial vision system after reflection or transmission by the optical element (3), and recombined in the form of a single composed image.
