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.

Abstract: A cone-of-light projection system projects a shell of laser light (or other electromagnetic radiation) using a fiber-optic bundle. Incidence optics directs a laser beam to be incident to the fiber-optic bundle at a predetermined angle of incidence, resulting in the projection of a conical shell of light. For the exemplary embodiment, the angle of incidence is non-orthogonal to the fiber-optic bundle, resulting in the projection of a conical shell of light. Thus, the laser projection technique converts a beam of laser light (or other electromagnetic radiation such as UV, visible, IR or microwave radiation) into a conically extending shell of light that in the exemplary embodiment is substantially conical. In one application, the laser projection technique can be used in industrial applications to assist in joining a cylindrical element to another surface.

Abstract: A highly versatile optical mount fabricated from a single solid structural body provides accurately centered secured fixturing of a large array of optical components or objects. Fixturing is provided by a unique screw-tensioned strapping mechanism.

Abstract: A ribbon-of-light projection system projects a substantially uniform ribbon of laser light (or other electromagnetic radiation) using a fiber-optic bundle, plano-mirrors, and a plano-cylindrical lens. Incidence optics directs a laser beam to be incident to the fiber-optic bundle at a predetermined angle of incidence, resulting in the projection of a sheet of light. The sheet of light is then projected towards the cylindrical lens where it is collimated into a ribbon. For the exemplary embodiment, the angle of incidence is orthogonal to the fiber-optic bundle. Thus, the laser projection system converts a beam of laser light (or other electromagnetic radiation such as UV, visible, IR or microwave radiation) into a collimated ribbon of light that in the exemplary embodiment is substantially uniform. In one application, the laser projection technique can be used in industrial applications to monitor the flow of fluids.
