    摘要: A glide height tester for inspecting a surface of a spinning magnetic disk includes a glide plate, which is mounted to pivot above the disk surface. A reflective surface fastened to the glide plate is imaged by interferometric apparatus which produces a calculated output indicating a first angle of the glide plate. The interferometric apparatus includes a Wollaston prism, which can be rotated 90-degrees to provide an output indicating a second angle of the glide plate, perpendicular to the first angle.

    摘要: An interferometer forms a pair of projected sub-beams by decomposing a single coherent, linearly-polarized beam. These sub-beams are focussed by an objective lens onto a pair of test spots on a test surface. The reflections of these sub-beams are recombined to form an elliptically polarized return beam, which is broken into return sub-beams of opposing polarities in a polarizing beam splitter. The intensities of these return sub-beams are used to calculate a difference in height between the two test spots. When these test spots are aligned along a path of relative motion with the test surface, the resulting differences in height are added to form an accumulative profile of the test surface.
