    摘要： A technique for comparing master parts with replicas to determine differences in shapes or sizes, is disclosed, which uses interferometric techniques as disclosed. A television camera is used to scan the pattern established by illuminating the subject with a set of optical fringes. An objective lens images these on a transmission line grating. A television camera scans the transmission grating. The spatial frequencies of the subject fringes and of the grating are especially selected so that the camera can not resolve either of them but can resolve their difference. As a result, the output signals of the camera represent a contour map of the object placed on a low frequency spatial carrier, but yet, the measurement sensitivity is still determined by the spatial frequency of the subject fringes.

    摘要： A XY control system for controlling vector movement in two mutually perpendicular directions (for example for computer cursor control, i.e. emulating a conventional computer mouse) uses a XY pressure sensitive digital pad or more preferably a XYZ pressure sensitive digital pad generating different signals based on the selected location at which pressure is applied to the pad. These signals are divided into X or Y and a directional signal and then converted into a velocity signal for controlling the vector motion in the required direction dependent on the selected location for application of pressure to the pad and at a velocity the magnitude of which is proportional to the displacement of the selected location from a datum area on the pad, or in the case of a XYZ pad dependent on both displacement and the amount of pressure applied at the selected location.
