Scanning-light-sheet apparatus designed to measure linear and angular displacement or deflection of structure. Intended specifically to measure deflection of beam-shaped truss structure. Includes conventional low-powered laser, lenses, mounts, single-axis optical scanner, several photodiodes, and electronic controller. Apparatus measures motion of structure and also used to determine positions, deflections, and velocities. Besides use in aerospace field, displacement measurements have many applications in construction-equipment and automotive industries.
