Abstract
A sealed housing having a pair of axially aligned front and rear apertures defining a line of sight through the housing, with two facing mirrors disposed within the housing adjacent the front aperture, the mirrors being perpendicular to the line of sight and parallely spaced apart from one another, with one of the mirrors extending into the line of sight and being semi-transparent in the line of sight area. A pair of light emitting elements are disposed within the housing below the line of sight and on either side thereof, such that upon their operation a viewer looking into the front aperture will appear to see an endless series of light flashes directed outwardly along the line of sight and being superimposed in the field of view so as to converge on a remote object with flashes of diminishing size or intensity as seen through the rear aperture. A further embodiment is provided wherein the facing mirrors are disposed on one side of the line of sight, and a further transparent mirror is disposed on the line of sight in a predetermined angular relationship with the image appearing on the surface of one of the transparent mirrors so as to super-impose the image appearing on the facing mirrors on the line of sight.
