Abstract

The invention is directed to a device utilizing electromagnetic energy, within or close to the visible frequency range, and components sensitive to such energy to determine, indicate and record, without use of photographic technique or TV video recording, the aim of an object relative to a defined point at a defined instant or variations in aim during a defined time interval.

One characteristic feature of the device is that an available aiming aid, for instance a telescopic sight, is used to pick up energy radiated from the point towards which the object should be aimed.

Claims

1. For use in a system for training personnel in aiming and firing weapons, said system comprising a weapon;

a telescopic sight affixed to said weapon in aiming alignment therewith; and

a target, free of wire and radio connections and disposed in spaced independent relationship to said weapon and visible through said sight, said target having means associated therewith at a defined point thereupon for emitting electromagnetic energy at or close to a visible frequency therefrom for reception by said sight;

a device mounted to said weapon in cooperative coaction with said sight and comprising;

a semi-transparent reflective surface disposed within said sight at an angle relative to the longitudinal axis of said sight for receiving target-emitted energy thereupon and reflecting said energy therefrom;

energy sensing components strategically disposed to ultimately receive said reflected energy from said surface and discriminate the relative positioning thereof; and

means translating said discriminant diversion of energy into a visible pattern demonstrating whether the aim at the moment of firing is at the defined point and, if not, the deviation therefrom.

2. A device according to claim 1 having a conical reflecting member having an opening defined at the apex thereof and operatively interposed between said reflecting surface and said energy sensing components to receive reflected energy from said reflecting surface and discriminately divert said energy to one or more of said components in relation to whether said reflected energy impinges upon said conical surface or passes through said opening.

3. A device according to claim 2 in which one sensing component corresponding to a direct hit is disposed beneath said conical member and other sensing components corresponding to various misses are disposed in spaced circumferential relationship about said conical reflecting member.

4. A device according to claim 3 in which said reflective surface is flat.

5. A device according to claim 4 in which said flat reflective surface is disposed at an angle of 45°

relative to the longitudinal axis of said sight.

6. A device according to claim 3 having a lens member operatively interposed between said reflecting surface and said conical reflecting member to pass reflected energy from said surface to said conical member.

7. A device according to claim 1 including means producing an output providing said visible pattern during a defined time interval.

8. A device according to claim 1 including means producing an output to convert said visible pattern into a permanent record.

9. For use in a system for training personnel in aiming and firing weapons, said system comprising a weapon;

a telescopic sight affixed to said weapon in aiming alignment therewith; and

a target, free of wire and radio connections and disposed in spaced independent relationship to said weapon and visible through said sight, said target having means associated therewith at a defined point thereupon for emitting electromagnetic energy at or close to a visible frequency therefrom for reception by said sight;

a device mounted to said weapon in cooperative coaction with said sight and comprising;

a semi-transparent reflective surface disposed within said sight at an angle relative to the longitudinal axis of said sight for receiving target emitted energy thereupon and reflecting said energy therefrom;

electromagnetic energy sensing elements strategically disposed in a minute area in the path of said reflected energy to receive said reflected energy from said surface, detect the diversion thereof and translate said discriminant diversion of energy into a visible pattern demonstrating whether the aim at the moment of firing is at the defined point and, if not, the deviation therefrom.

10. A device according to claim 9 in which said reflective surface is flat.

11. A device according to claim 10 in which said flat reflective surface is disposed at an angle of 45°

relative to the longitudinal axis of said sight.

12. A device according to claim 9 having a lens member operatively interposed between said reflecting surface and said electromagnetic sensing elements to pass reflected energy from said surface to said elements.

13. A device according to claim 9 including means producing an output providing said visible pattern during a defined time interval.

14. A device according to claim 9 including means producing an output to convert said visible pattern into a permanent record.

15. For use in a system for training personnel in aiming and firing weapons, said system comprising a weapon;

a telescopic sight affixed to said weapon in aiming alignment therewith; and

a target, free of wire and radio connections and disposed in spaced independent relationship to said weapon and visible through said sight, said target having means associated therewith at a defined point thereupon for emitting electromagnetic energy at or close to a visible frequency therefrom for reception by said sight;

a device mounted to said weapon in cooperative coaction with said sight and comprising;

a semi-transparent reflective surface disposed within said sight at an angle relative to the longitudinal axis of said sight for receiving target emitted energy thereupon and reflecting said energy therefrom;

a plurality of optic fiber conductors having their ends compacted into a minute area strategically disposed in the path of said reflected energy to receive said reflected energy from said surface and discriminate between those beams which are on center and off-center to produce a visible pattern demonstrating whether the aim at the moment of firing is at the defined point and, if not, the deviation therefrom.

16. A device according to claim 15 in which said reflective surface is flat.

17. A device according to claim 16 in which said flat reflective surface is disposed at an angle of 45°

relative to the longitudinal axis of said sight.

18. A device according to claim 15 including means producing an output providing said visible pattern during a defined time interval.

19. A device according to claim 15 including means producing an output to convert said visible pattern into a permanent record.

20. A device according to claim 15 having a lens member operatively interposed between said reflective surface and said optic fiber conductors to pass reflected energy from said surface to said conductors.
