Abstract
A method for manufacturing an image projection device for projecting an image onto an eye, includes an emission surface S. The surface S comprises a set of waveguides, a set of diffraction gratings and a set of electrodes. Each grating is positioned at the intersection of one of the guides and one of the electrodes so as to form an emission point for a light wave, the set of waveguides being arranged in a waveguide configuration, and the set of electrodes being arranged in an electrode configuration. The method comprises a phase of designing the device and a phase of physically manufacturing the device thus designed. The design phase comprises the step consisting in determining the waveguide configuration or the electrode configuration, the determined configuration being a non-rectilinear isoline configuration defined in the plane defined by the emission surface S and generating an aperiodic distribution of the emission points.
