Abstract Nondiffracting cos beams may be used in the object space of an optical microscope for causing a nonuniform illumination. This irradiance distribution consists in a set of equidistant plane maxima, and therefore the light radiated by the sample decays in its neighborhood. We propose to observe over an object plane coinciding with one of these illumination peaks, which results in a superresolving axial effect. For that purpose, illumination and detection should be oblique processes, and a computer-assisted z-scanning process is needed in order to access the axial structure of a thick object.
