A holographic sight and a method for providing a virtual image for a holographic sight

Abstract

A holographic sight (100) wherein the holographic sight (100) comprises a light engine (140) configured to produce a set of image bearing light beams (180) and a transparent waveguide (110). The transparent waveguide (110) further comprises a first in-coupling structure (120) configured to receive and couple the set of image bearing light beams (180) into the transparent waveguide (110) as a first set of guided beams (182) and a first out-coupling structure (130) configured to receive and couple out the first set of guided beams (182) as a first virtual image (184) into a first eyebox (150). The holographic sight (100) further comprises image adjustment means (145) configured to adjust position of the first virtual image (184) in the first eyebox (150).
