Abstract

The disclosure relates to a viewing optic. In one embodiment, the disclosure relates to a viewing optic having an integrated display system. In one embodiment, the disclosure relates to a viewing optic having an integrated display system for generating images that are projected into the first focal plane of an optical system.

First claim

What is claimed is:

1. A viewing optic comprising:
a body having an objective lens system at one end configured to focus a target image from an outward scene,
an ocular lens system at the other end of the body and a movable erector tube with an erector lens system located between the objective and ocular systems, the erector lens system, the objective lens system and the ocular lens system configured to form a first optical system having a first focal plane with a first reticle at the first focal plane configured to move in conjunction with the movable erector tube;
a beam combiner located between the first reticle and the objective lens system; and
an active display configured to generate an image, a lens system configured to collect light from the active display, wherein the lens system is located between the active display and a reflective material, the reflective material configured to direct the image from the active display to the beam combiner, wherein the reflective material is located between the lens system and the beam combiner, and further wherein the image from the active display and the target image from the objective lens system are combined into the first focal plane and viewed simultaneously, and further wherein the image from the active display is not tied to movement of the erector tube.

2. The viewing optic of claim 1 , wherein the image is a digital reticle.

3. The viewing optic of claim 1 , wherein the beam combiner is located from 5 to 25 mm from the objective lens system.

4. The viewing optic of claim 1 further comprising a focusing cell located between the beam combiner and the objective lens system.

5. The viewing optic of claim 4 further comprising a rod connecting the focusing cell to a parallax adjustment knob.

6. The viewing optic of claim 5 wherein the rod is from 25 to 33 mm in length.

7. The viewing optic of claim 1 , wherein the lens system has an inner lens cell and an outer lens cell.

8. The viewing optic of claim 7 , further comprising a spring located between the inner lens cell and the outer lens cell.

9. The viewing optic of claim 7 , wherein the inner lens cell is located within 2 mm of the active display.

10. The viewing optic of claim 1 , wherein the active display is selected from the group consisting of: a transmissive active matrix LCD display (AMLCD), an organic light-emitting diode (OLED) display, a Light-Emitting Diode (LED) display, a e-ink display, a plasma display, a segment display, an electroluminescent display, a surface-conduction electron-emitter display, and a quantum dot display.

11. The viewing optic of claim 1 , wherein the image generated by the active display is selected from the group consisting of: text, alpha-numeric, graphics, symbols, video imagery, icons, active target reticles, range measurements, wind information, GPS and compass information, firearm inclination information, target finding, recognition and identification (ID) information, external sensor information, temperature, pressure, humidity, real time ballistic solutions, and next round ballistic correction through in-flight tracer round detection and tracking.

12. The viewing optic of claim 1 , wherein the reflective material is a mirror.

13. The viewing optic of claim 12 , wherein the mirror is angled from about 40° to about 50° relative to the emitted light of the active display.

14. The viewing optic of claim 1 , further comprising a controller configured to selectively power one or more display elements to generate the digital image.

15. The viewing optic of claim 1 , further comprising a laser range finder coupled to a top portion of the body.

16. A viewing optic comprising: (a) a main tube; (b) an objective system coupled to a first end of the main tube configured to focus a target image from an outward scene; (c) an ocular system coupled to the second end of the main tube, the main tube, objective system and ocular system being configured to define at least a first focal plane, with a first reticle at the first focal plane that moves in relation to a turret adjustment; (d) a beam combiner positioned between the objective system and the first focal plane; and (e) an active display configured to generate an image, and (f) a lens system located between the active display and the beam combiner and configured to collect light from the active display, wherein the image from the active display and the target image are combined into the first focal plane, and further wherein the image from the active display is unaffected by a turret adjustment.

17. The viewing optic of claim 16 , further comprising a reflective material configured to direct the generated image to the beam combiner.

18. The viewing optic of claim 16 , wherein the beam combiner is located from 5 to 25 mm from the objective system.
