This citation summarizes a one-page announcement of technology available for utilization. Objects in free fall are viewed at constant magnification by an optical carriage mechanism. The object is viewed continuously by a movie or TV camera for studies of the dynamics of free fall. A prototype is used in experiments on the nuclear fuel pellets as they fall under the influence of gravity. As shown in the figure, the system consists of an optical carriage on a vertical track and a fixed telescope that is attached to a camera. The carriage holds a lens that collimates rays of light reflected from the falling object. The carriage has been used to track falling glass spheres about 2 cm in diameter over a vertical distance of 2 m. ...FOR ADDITIONAL INFORMATION: Contact: The Patent Counsel, NASA Resident Office-JPL, Jet Propulsion Laboratory, Pasadena, CA.
