Abstract: An improved method and apparatus for aligning laser systems to optical systems at long distances. An embodiment of this uses a reflective material with markings which reflects light back along its angle of incidence to permit a user to align the two systems.

Abstract: Optical systems are described that use one or more lasers to project images onto a screen or projection surface. The optical systems can be direct view optical systems or vision projection optical systems. The described systems reduce costs and power consumption compared to the use of optical systems that use LCD screens. In addition, the described optical systems permit the image to be displayed anywhere on the screen, which in turn allows the screen to have improved light transmission for enhanced target identification in the case of gun/weapon sights and other devices that are used for target recognition.
