Moving target screen with improved optical control

Claim 1

An electro-optical weapon firing training apparatus comprising a film projector and viewing screen, at least one weapon on which is mounted a laser means to trigger an infrared energy laser beam aimed toward said screen upon firing said weapon; said projector including optical means for projecting the images of said film for providing a target scene on said screen at which said weapon may be aimed to direct a laser beam thereat, and said screen reflecting said laser beam, said optical means including an optical lens and a dichroic mirror positioned in the path of the projected images, said dichroic mirror being positioned at an angle with respect to the plane of said lens for allowing a major part of the visible light to pass therethrough onto said screen while reflecting the remainder of said visible light in a direction away from said lens, infrared energy detection means, a first surface mirror moveably mounted in a position to receive the laser beam reflected from said screen and to reflect said laser beam onto said angled dichroic mirror, and said dichroic mirror further reflecting said laser beam energy through said lens to said detector means.
