title: Some further aspects of scatter-fringe interferometry.
abstract: It is shown that an interferometer using one scatter plate and a plane mirror is well suited for testing long focus optical systems. Stability is automatically achieved in this system because of its +1 magnification. Two methods of introducing straight fringes into the field in order to examine a nearly perfect optical system, and a method of making scatter plates to give high-contrast fringe patterns are described.
