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