The invention relates to a method for measuring optical aberrations with variable range and sensitivity using two reconfigurable optical elements and to a device for performing same. The wavefront (A) to be analysed hits a sampling sub-system (1) that includes a reconfigurable optical element (11) which provides an irradiance pattern (P) that has a controllable position and shape and can be used to measure the aberration. According to the invention, a sub-system (2), which contains another reconfigurable optical element (21), forms an image (I) of the pattern (P) on a fixed plane (3). A detector (4) is disposed on said plane and connected to an analysis sub-system (5) which calculates the aberration (F) of the front (A). A sub-system (6) controls the properties of the reconfigurable elements (11 and 21). Consequently, it is not necessary for the detector to be moved mechanically in order to place same in the variable position in which the pattern (P) is formed.
