Night vision goggles with enhanced display

Abstract

The invention relates to a night vision scope (10) comprising: a camera lens (SL) and a light intensifier device (ILD) including a screen (E) on which an image called the amplified image (Iamp) is displayed; a first optical system (OS1) for image transport and inversion including at least one lens, having an optical axis (OA) and configured to produce a curved intermediate image (Iint) of said amplified image, said curved intermediate image being located on a curved image surface (SIC); a first transparent display (TD1) having an annular peripheral zone (ZPA) disposed in the vicinity of said curved image surface and configured to display information, said information being superimposed on the intermediate image; an eyepiece (EP) configured to form an upright image of said intermediate image; the first optical system and the eyepiece forming the overall optical system of the scope.

Claims

the intermediate image, at least part of said information being located in a part of the peripheral zone of the first display outside the field of the intermediate image.

8. Glasses according to one of the preceding claims in which the overall optical system comprises an optical path comprising an optical combiner (Comb), a second optical system (SO2) and a second display (Disp) configured so that an image of the second display (12) is merged with the intermediate image.

9. Glasses according to one of the preceding claims in which the first optical system (OS1) comprises a first optical field group (GO1) arranged in front of the first display and a second optical aperture group (GO2) forming said intermediate image, and in which the eyepiece comprises a third optical group (GO3) arranged in the vicinity of said intermediate image and a fourth optical group (GO4).

10. Glasses according to the preceding claim in which the overall optical system comprises an optical path comprising an optical combiner (Comb) arranged between the first optical group and the second optical group, a second optical system (OS2) and a second display (Disp), the image of the second display produced by the second optical system, the optical combiner and the second optical group being merged with said intermediate image.

11. Glasses according to one of the preceding claims further comprising a third transparent display (TD2) having a central zone (ZC) arranged in the vicinity of said curved image surface and configured to display information. 3 / 13 CM CM [Fig. 7] [Fig. 9] 10 / 13 amp 11 / 13 F\n 4 ILx l I [Fig. 12]
