Abstract

The present invention is directed to a laser assisted telescopic targeting system, apparatus and method of range finding and aiming a projectile firing weapon. The invention includes a laser light generating source capable of producing a spot of laser light on a target. The invention also includes a shooting scope to view the target. The shooting scope preferably has indicia or a shutter for measuring the approximate size of the laser dot projected on the target. Based upon the size of the spot and the growth rate of the laser targeting source the user can determine, with a substantial degree of accuracy, the relative distance from the target. The method includes steps associated with using the inventive apparatus and system and aiming a projectile firing weapon depending upon the information obtained.

Claims

1. A laser assisted telescopic targeting device, comprising:

a shooting scope;

laser means, positioned substantially parallel to the shooting scope for projecting a beam of laser light toward a target enabling a spot of laser light to appear thereon and remain within a field of view associated with the shooting scope; and

sizing means for determining the approximate size of the spot of laser light;

as viewed through the shooting scope and projected on the target by the laser means enabling a user to determine the relative distance the spot of laser light is from the laser means.

2. The device of claim 1, wherein:

the sizing means is configured to enable the user to adjust the point of aim of the projectile firing weapon to maximize the accuracy of the user of the projectile firing weapon.

3. The laser assisted targeting device of claim 1, wherein the sizing means further includes:

indicia associated with the shooting scope.

5. The laser assisted targeting device of claim 1, wherein:

the shooting scope is selected from the group of shooting scopes consisting of handgun scopes, riflescopes, archery scopes, and crossbow scopes.

6. The laser assisted targeting device of claim 3 wherein:

the indicia is selected from the group consisting of reticles, circles, crosshairs, dots, and lines.

7. The laser assisted targeting device of claim 3, wherein:

the indicia is provided to determine the size of the spot of laser light on the target and provide various sight lines.

8. The laser assisted targeting device of claim 1, wherein:

the shooting scope and laser means are contained within a single housing.

9. The laser assisted targeting device of claim 1, further including:

a projectile firing weapon.

4. A laser assisted targeting device, comprising:

a shooting scope;

laser means for projecting a beam of laser light toward a target enabling a spot of laser light to appear thereon; and

sizing means for determining the approximate size of the spot of laser light projected on the target by the laser means enabling a user to determine the relative distance the spot of laser light is from the laser means; and

wherein the sizing means further includes shutter means having an aperture variable in size for measuring the size of the spot of laser light projected on the target by the laser means.

10. A laser assisted telescopic point of aim system, comprising:

scope means for viewing a target along a sight line;

laser means for generating a beam of laser light incident upon the target and substantially parallel with the sight line enabling a spot of laser light to appear on the target, and remain within a field of view associated with the scope means; and

means for measuring the approximate size of the spot of laser light incident upon the target as viewed through the scope means and enabling the user to determine the approximate distance the scope means is from the target by reference to known growth data of the laser means.

11. The system of claim 10, wherein:

the system if further configured to enable the user to adjust the point of aim of a projectile firing weapon to increase the accuracy of a fired projectile.

12. The laser assisted point of aim system of claim 10, wherein the means for measuring includes:

indicia associated with the shooting scope.

14. The laser assisted point of aim system of claim 10, wherein:

the scope means is a shooting scope selected from the group of shooting scopes consisting of handgun scopes, riflescopes, archery scopes, and crossbow scopes.

15. The laser assisted point of aim system of claim 10, wherein:

the indicia is selected from the group consisting of reticles, circles, crosshairs, dots, and lines.

16. The laser assisted point of aim system of claim 10, wherein:

the scope means and laser means are separate components.

18. The laser assisted point of aim system of claim 10, further including:

heat sensing means for detecting the presence of a mammalian target.

13. A laser assisted point of aim system, comprising:

scope means for viewing a target;

laser means for generating a beam of laser light incident upon the target;

enabling a spot of laser light to appear thereon; and

means for measuring the approximate size of the spot of laser light incident upon the target enabling the user to determine the approximate distance the scope means is from the target by reference to known growth data of the laser means; and

wherein the means for measuring further includes a shutter.

17. The laser assisted point of aim system of claim 13, wherein:

the scope means and the laser means are contained within a single housing.

19. A method of aiming a projectile firing weapon, including the steps of:

viewing a target along a sight line with a shooting scope;

positioning a source of laser light substantially parallel to the shooting scope

projecting a beam of laser light on the target and substantially parallel with the sight line enabling a spot of laser light to appear thereon, and remain within a field of view associated with the shooting scope;

determining the approximate size of the spot of laser light projected on the target as viewed through the shooting scope; and

determining the relative distance to the target based upon the size of the spot and the growth rate of the beam of laser light projected by reference to know growth data of the spot of laser light.

20. The method of claim 19, including the step of:

adjusting the line of sight of a projectile firing weapon in response to the determined distance.

22. The method of claim 19, wherein the step of determining the approximate size further includes:

comparing the size of the spot to predetermined indicia visible through the shooting scope.

21. A method of aiming a projectile firing weapon, including the steps of:

viewing a target with a shooting scope;

projecting a beam of laser light on the target enabling a spot of laser light to appear thereon;

determining the approximate size of the spot of laser light projected on the target; and

determining the relative distance to the target based upon the size of the spot and the growth rate of the beam of laser light projected by reference to known growth data of the spot of laser light at varying distances; and
