The invention concerns a device for observing a body, in particular a viewer, comprising means for illuminating (12) the body (5), means for sampling (400, 450, 500, 700) light coming from an illuminated site (01) of the body and compensating means (20) for measuring a deformation of the wave front of a beam coming from a point of the body (5) and for applying to the light sampled by the sampling means (400, 450, 500, 700) a correction calculated on the basis of said measured deformation. The invention is characterised in that the sampling means and the compensating means are arranged such that, for each point of the body used for calculating the correction, the sampling means sample the light on a selected zone of the body near enough to said calculation point for the deformation of the wave front of the light coming from any point of that zone should be the same as that coming from the point of calculation more or less within a wavelength fraction, and the device includes means (400, 450, 500, 700) for automatically changing the point of the body (5) used for the calculation of correction and for changing synchronously the associated sampling zone, such that the device scans the observed body by way of a series of such successive zones for each of which the deformation of the wave front derived from any point in the zone is identical, more or less within a wavelength fraction, to the deformation of the wave front derived from the associated point of calculation.

L'invention concerne un dispositif d'observation d'un corps, notamment d'un oeil, comportant des moyens d'illumination (12) du corps (5), des moyens de prélèvement (400, 450, 500, 700) de la lumière provenant d'un endroit illuminé (01) du corps (5) et des moyens de compensation (20) aptes à mesurer une déformation de front d'onde d'un faisceau provenant d'un point du corps (5) et à appliquer à la lumière prélevée par les moyens de prélèvement (400, 450, 500, 700) une correction calculée à partir de cette déformation mesurée, caractérisé en ce que les moyens de prélèvement et les moyens de compensation sont agencés de sorte que, pour chaque point du corps utilisé pour un calcul de correction, les moyens de prélèvement prélèvent la lumière sur une zone du corps choisie suffisamment voisine dudit point de calcul pour que la déformation de front d'onde de la lumière provenant de tout point de cette zone soit la même que celle provenant du point de calcul à une fraction de longueur d'onde près, et en ce que le dispositif inclut des moyens (400, 450, 500, 700) pour changer automatiquement le point du corps (5) utilisé pour le calcul de correction et changer, en synchronisme, la zone de prélèvement associée, de telle sorte que le dispositif balaie le corps observé sous la forme d'une série de telles zones successives pour chacune desquelles la déformation du front d'onde émanant de tout point de la zone est identique, à une fraction de longueur d'onde près, à la déformation du front d'onde émanant d'un point de calcul associé.
