Holographic sporting/combat optic with reticles recorded at different distances
View Patent ↗A holographic sporting/combat optic may be mounted to weapon. The holographic sporting/combat optic includes a laser diode, a holographic recording element and one or more optical components arranged in a housing. In response to a light beam incident thereon, the holographic recording element projects a composite, multidimensional reticle image into the optical viewing window. Of note, the holographic recording element has two or more reticle elements recorded thereon which form the composite reticle image. Each of the two or more reticle elements is captured at a different distance from the weapon during different exposures of the holographic recording element.
1. A holographic sporting/combat optic suitable for use with a particular weapon, comprising:
a housing defining an optical viewing window and configured to mount to the particular weapon;
a laser diode supported in the housing and operable to emit a beam of light;
a holographic recording element projects a composite reticle image in the optical viewing window and along a line of sight axis in response to a light beam incident thereon, the holographic recording element having two or more reticle elements recorded thereon and forming the composite reticle image, such that the two or more reticle elements are captured during different exposures of the holographic recording element and at different distances from the particular weapon; and
one or more optical components arranged in the housing to direct the beam of light from the laser diode onto the holographic recording element.
2. The holographic sporting/combat optic of claim 1 wherein each of the two or more reticle elements recorded on the holographic recording element corresponds to a known ballistic reference point for the particular weapon.
3. The holographic sporting/combat optic of claim 1 wherein one of the two or more reticle elements corresponds to a known ballistic reference point for a first weapon and another of the two or more reticle elements corresponds to a known ballistic reference point for a second weapon that differs from the first weapon.
4. The holographic sporting/combat optic of claim 1 wherein each of the two or more reticle elements recorded on the holographic recording element corresponds to a known blast radius or a known trajectory arc for a particular explosive ammunition.
5. The holographic sporting/combat optic of claim 1 the holographic recording element has ballistic reference data for the particular weapon recorded thereon and projects the ballistic reference data in the optical viewing window but outside of a viewing area of the target scene that surrounds the composite reticle image.
6. The holographic sporting/combat optic of claim 5 wherein the ballistic reference data includes a descriptor for the particular weapon and, for each of the two or more reticle elements, an indicia for a given reticle element and a corresponding distance at which the given reticle element was captured at when recorded on the holographic recording element.
7. The holographic sporting/combat optic of claim 1 wherein the viewing area of the target scene is defined 45 degrees either side of the line of sight axis and the ballistic reference data is projected in an area offset more than 45 degrees from the line of sight axis.
8. The holographic sporting/combat optic of claim 1 wherein the one or more optical components includes a collimating lens configured to receive the light beam from the laser diode and collimate the light beam, and a diffraction grating configured to receive the collimated light beam from the collimating lens and direct the collimated light beam towards the holographic recording element.
9. A holographic sporting/combat optic suitable for use with a particular weapon, comprising:
a housing defining an optical viewing window and configured to mount to the particular weapon;
a laser diode supported in the housing and operable to emit a beam of light;
a holographic recording element, in response to a light beam incident thereon, projects a composite reticle image along a line of sight axis in the optical viewing window and projects ballistic reference data for the particular weapon adjacent to the composite reticle image, wherein the composite reticle image is recorded on a first plane of the holographic recording element and the ballistic reference data is recorded on a second plane of the holographic recording element that differs from the first plane; and
one or more optical components arranged in the housing to direct the beam of light from the laser diode onto the holographic recording element.
10. The holographic sporting/combat optic of claim 9 wherein the holographic recording element has at least two reticle elements forming the composite reticle image, such that each of the at least two reticle elements is captured at a different distance from the particular weapon.
11. The holographic sporting/combat optic of claim 10 wherein the ballistic reference data includes an indicia for each of the at least two reticle elements and a corresponding distance at which the reticle element was captured when recorded on the holographic recording element.
12. The holographic sporting/combat optic of claim 9 wherein the ballistic reference data includes a descriptor for the particular weapon.
13. The holographic sporting/combat optic of claim 12 wherein the ballistic reference data further includes a type of ammunition, a distance from the particular weapon, and a measure of deviation from the line of sight axis at the corresponding distance by a projectile fired by the particular weapon.
14. The holographic sporting/combat optic of claim 10 wherein each of the two or more reticle elements recorded on the holographic recording element corresponds to a known blast radius or a known trajectory arc for a particular explosive ammunition.
