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 during hunting comprising:

a. providing a bow,

b. providing an arrow mounted onto the bow,

c. providing an arrow tip having a bladed first end and attached to the arrow at a second end,

d. providing a laser integrated into the arrow tip such that a laser beam is emitted through an aperture at the first end of the arrow tip and is substantially coaxial with the arrow,

e. whereby the laser, the arrow tip, and arrow are to be shot from the bow.

2. The method of claim 1 wherein the aperture comprises an optically transparent window.

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

4. An archery projectile for hunting comprising:

a. an arrow,

b. an arrow tip having a bladed first end and a means for attaching to the arrow at a second end, and

c. a laser integrated into the arrow tip such that a laser beam is emitted through an aperture at the first end of the arrow tip and substantially coaxial with the arrow.

5. The archery projectile of claim 4 wherein the aperture comprises an optically transparent window.

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