Abstract

The laser targeting system of the present invention eliminates the problem of parallax between the arrow'"'"'s path and the archer'"'"'s line of sight. An embodiment is a laser integrated into an arrow such that the beam is projected down the axis of the arrow. Another embodiment is an arrow rest with an integrated laser, which can have an angular adjustment. By having the laser extend the axis of the arrow to the target, the laser spot produced on the target accurately represents where the arrow will hit once released, and eliminates the parallax angle between the archer'"'"'s line of sight and the arrow'"'"'s path. The present invention also provides a means for using a single laser beam to project a diffractive pattern onto a target, such as several spots or crosshairs. For advanced visibility of the laser spot, an optical filter or infrared vision optical sensors can be used.

Claims

1. A method for eliminating aiming parallax comprising:

a. providing a bow

b. providing an archery projectile mounted onto the bow

c. providing a laser integrated into the projectile such that a laser beam is emitted substantially coaxial with the projectile

d. whereby the archery projectile and the integrated laser are to be shot from the bow.

3. The method of claim 1 wherein the laser beam passes through a diffractive element integrated into the projectile before being emitted from the projectile.

2. (canceled)

4. An archery projectile to be shot from a bow comprising a laser integrated into the projectile such that X a laser beam is emitted substantially coaxial with the projectile.

6. The archery projectile of claim 4 wherein the laser beam passes through a diffractive element integrated into the projectile before being emitted from the projectile.

5. (canceled)

7. A method for enhancing visibility of archery lasers comprising the viewing of Me a laser beam through an optical filter designed to pass the wavelength of the laser beam and attenuate other regions of the visible spectrum.

8. An archery sight comprising an optical filter designed to pass the wavelength of tee a laser beam shone on a target and attenuate other regions of the visible spectrum.

9. The archery sight of claim 8 adapted for attachment to a bowstring.

10. A method for enhancing the visibility of archery lasers comprising the viewing of a laser beam through a night vision scope.

11. An archery sight comprising a night vision scope designed to enhance the visibility of a laser beam.

12. An arrow rest comprising a laser integrated into a rest where an arrow sits, such that a laser beam is emitted substantially parallel with the shaft of the arrow.

13. The arrow rest of claim 12 wherein the laser beam is projected parallel with an archery projectile.

14. The arrow rest of claim 12 wherein the laser beam passes through a diffractive element integrated into the arrow rest before being emitted from the arrow rest.

15. The arrow rest of claim 12 wherein the laser can be adjusted for aiming beyond the flat-trajectory range.
