The invention provides an optical instrument including means (1, 2) to produce an optical image to be viewed by an observer including a diffractive element (7) located at an intermediate focal or image plane (4) of the optical instrument and comprising a pattern of a plurality of areas effective to cause diffraction interference in light passing through the optical instrument and thereby produce an expanded exit pupil (6) comprising a combination of a multiplicity of exit pupils displaced relative to one another transverse to an optical axis (3) of said instrument.
L'invention concerne un instrument optique pourvus de moyens (1, 2) permettant de produire une image optique destinée à être visualisée par un observateur. Ledit instrument optique, qui comporte un élément (7) de diffraction placé au niveau d'une focale intermédiaire ou d'un plan image (4) de l'instrument optique, comprend un motif, constitué d'une pluralité de zones, qui sert à produire des interférences de diffraction dans la lumière traversant l'instrument optique, ce qui permet de réaliser une pupille (6) de sortie élargie comprenant une multitude de pupilles de sortie combinées qui se déplacent les unes par rapport aux autres transversalement à un axe optique (3) dudit instrument.
