ABSTRACT:
A focusing, collimating, and beamsplitting test system for testing laser rangefinders for their beam quality, ranging accuracy, and sight unit alignment. The system includes holographic optical elements in place of conventional mirrors, lenses and beamsplitters. The advantages of this system are that it not only reduces the size and weight of optical elements, but also reduces the number of required elements. Consequently, the resulting test equipment requires less labor to assemble and is more compact and much lighter than conventional test systems.
