ABSTRACT:
A riflescope or other telescope is used as a target projector and as a collecting telescope for the reflected light. The light source is placed at the usual eye position of the telescope, projected through the ocular and then through the objective lens of the telescope. The reflected beam is recollected by the objective lens and forms an image on the telescope reticule. The image is presented to the eye through the ocular and a beamsplitter.
