    Abstract: A method is used for detecting a tilt of an optical pickup head. The method includes the steps of: capturing a plurality of images; converting the images to bitmap images; superposing the bitmap images together to form an superimposed bitmap image; setting a two-dimensional coordinating system of the superimposed bitmap image; determining coordinates of a first static spot, a second static spot, and dynamic spot; calculating a first distance between the first static spot and the dynamic spot, and a second distance between the second static spot and the dynamic spot based on the coordinates to determine a maximum distance; and comparing the maximum distance with a first standard distance to attain a conclusion whether the tilt is in an acceptable range.

  • Method for characterizing transparent thin-films using differential optical sectioning interference microscopy
    Publication number: 20080266548
    Abstract: An imaging, differential optical sectioning interference microscopy (DOSIM) system and method for measuring refractive indices and thicknesses of transparent thin-films. The refractive index and thickness are calculated from two interferometric images of the sample transparent thin-film having a vertical offset that falls within the linear region of an axial response curve of optically sectioning microscopy. Here, the images are formed by a microscope objective in the normal direction, i.e., in the direction perpendicular to the latitudinal surface of the thin-film. As a result, the lateral resolution of the transparent thin-film is estimated based on the Rayleigh criterion, 0.61?/NA.
