Head-up display and its use in a helmet-mounted sighting instrument

摘要

the device consists of a spherical mirror comprising a holographic optical assembly used on the axis (31), and a semi transparent mirror (32).the light image generator (1, 2) has a first radiation face is on the convex spherical mirror, is returned, and then by the semi transparent mirror in the direction of the spherical mirror, which includes ru00e9flu00e9u00adchit and finally to the observer.the optical collimation and combination is enclosed in a transparent medium (4) is formed by a glass slide with parallel faces forming a stigmatic optical infinity, for receiving the radiation from the scenery outside.;in particular, the achievement of the application scopes of the helmet.
