A method to evaluate wave-front aberrations in optical telescopes that is based on the method of curvature sensing but that solves the irradiance transport equation by variable separation is presented. This technique is simpler for processing than are previously released techniques and can perform more efficiently, as is required by active and adaptive optics. Testing for consistency of the method by evaluation of several sets of out-of-focus images obtained with the 2-m telescope at the Universidad Nacional Autonoma de Mexico was carried out, and a stability of 10% for the derived values of Zernike coefficients was found. curvature sensing, irradiance transport equation, active and adaptive optics.
