Abstract
The present disclosure provides an optical system comprising an objective positive lens and a negative eyepiece lens arranged coaxially to form a Galilean magnification system. A holographic optical element is positioned between the objective positive lens and the negative eyepiece lens. The holographic optical element includes a plurality of reticles, wherein each of the plurality of reticles is a multiplanar reticle focused at a different distance. The system may further include a replay light source configured to illuminate the holographic optical element to generate a converging beam. The converging beam passes through the negative eyepiece lens to create a virtual image at a virtual image distance.

An optical sighting system, comprising:
- an objective positive lens and a negative eyepiece lens arranged coaxially to form a Galilean magnification system;
- a holographic optical element positioned between the objective positive lens and the negative eyepiece lens;
- a plurality of reticles recorded in the holographic optical element, wherein each of the plurality reticles is a multiplanar reticle focused at a different distance.
A method of manufacturing a holographic optical element, comprising:
- providing a glass substrate;
- bonding a photosensitive material to the glass substrate;
- recording a first aiming reticle in the photosensitive material at a first focal distance;
- recording a second aiming reticle in the photosensitive material at a second focal distance;
- recording further aiming reticles in the photosensitive material at the further focal distances;
- and
- recording a range finding line in the photosensitive material with a focus that gradually transitions from a near distance to a far distance.
