Abstract
An optical targeting device comprised of a support body, an imaging waveguide joined to and in a position relative to the support body, and a light source mounted on the support body. The imaging waveguide is comprised of an input diffractive optic, and an output diffractive optic. The light source is located to direct a targeting light beam to the input diffractive optic of the imaging waveguide. In operation of the optical targeting device, the imaging waveguide simultaneously transmits incoming light from a scene viewable by a user of the device through the light transmissive body, and propagates the targeting light beam from the input diffractive optic laterally through the light transmissive body and directs the targeting light beam outwardly from the output diffractive optic, thereby rendering the targeting light beam as a point of light superimposed within the scene viewable by the user.
