摘要： The invention relates to a method for acquiring an image by an imager (20) comprising a matrix of pixels configured to generate an electric response when exposed to an incident light flux travelling through an optical path (21) in which is arranged a wavefront correction element (22), comprising the following steps: 1) initiating the exposure of the pixels to the incident light flux; 2) for a plurality of iterations during the exposure: 2.1) non-destructive reading of the electric responses of pixels of a region of interest; 2.2) determining an evolution of the spatial distribution of pixels in logarithmic mode previous iteration with respect to the previous iteration; 2.3) based on said evolution, establishing a command for the wavefront correction element (22) in order to correct the wavefront; 2.4) configuring the wavefront correction element, 3) reading the electric responses of the pixels resulting in an image.
