Abstract: Method for encapsulating at least partly a light-guide optical element in a transparent capsule, the method comprising at least: —a transparent capsule providing step during which a transparent capsule is provided, —a light-guide optical element providing step during which a light-guide optical element is provided, —an adhesive deposing step during which an adhesive is deposited on at least part of a face of the transparent capsule and/or of a face of the light-guide optical element, —a positioning step during which the transparent capsule and the light-guide optical element are positioned one relative to the other so as to form an optical system, —a bonding step during which the light-guide optical element and the transparent capsule are made integral with the adhesive, wherein the method further comprises prior to the bonding step a control step during which at least one parameter of the optical system is controlled.
