Abstract
A sighting or observation scope having a sighting or observation axis x includes, in a mechanical structure: a camera, a first video micro-display displaying an image of the external landscape acquired by the camera, referred to as first object a first eyepiece associated with the first video micro-display and forming a first image of the first object at infinity a first pupil-expansion light guide arranged optically downstream of the first eyepiece and designed to extend a pupil of the first eyepiece in two directions of space and to superimpose the first image on the external landscape.

A sighting or observation scope having a sighting or observation axis x and comprising, in a mechanical structure (SM):
- a camera (CI),
- a first video micro-display (MA1) displaying an image of the external landscape acquired by the camera, referred to as first object
- a first eyepiece (OC1) associated with the first video micro-display and forming a first image of the first object at infinity
- a first pupil-expansion light guide (PE1) comprising at least two first plane and parallel faces (FP1, FP1′), the first pupil-expansion light guide (PE1) being arranged optically downstream of the first eyepiece and designed to extend a pupil of the first eyepiece in two directions of space and to superimpose the first image on the external landscape, a structure of the first pupil-expansion light guide (PE1) being designed such that an overall size (Dx1) of the first pupil-expansion light guide (PE1) along the axis x is less than 2 cm.
