title: Modified Young's Interferometer.
abstract: A modified Young's two-slit interferometer measures the separation between the centers of two slits or two lines when they are nearly coincident. A prototype instrument, which functions as an automatic, interferometric micrometer, is described. This instrument measures the position of a slit with a resolution of 5 nm.
