    Abstract: A dimension measuring apparatus for measuring a dimension between a first contour data which is an evaluation reference of a pattern to be evaluated and a second contour data which is the pattern to be evaluated generates first correspondence information between a point on the first contour data and a point on the second contour data, determines consistency of a correspondence included in the first correspondence information, corrects an inconsistent correspondence, and generates second correspondence information, when associating a point on the first contour data and a point on the second contour data with each other.

  • Publication number: 20130098274
    Abstract: A sample stage device (10) is so configured as to calculate ideal position information xtg(i), tg(i) per predetermined period that is unaffected by drive conditions relating to gaps (25, 26), etc., and to determine, per predetermined cycle and in real time, deviations dx(i), dy(i) between real-time measured positions x(i), y(i) by position detectors comprising laser interferometers (33, 34), etc., and ideal position information xtg(i), tg(i). In addition, it calculates, based on deviations dx(i), dy(i) thus determined, such speed command values vx(i), vy(i) for motors (27, 28) that measured values x(i), y(i) would follow ideal position information xtg(i), tg(i), and performs stable and high-speed positioning control for a sample table (11) through feedback control that controls speed in real time.

  • Publication number: 20110274362
    Abstract: The objective is to improve a classification standard. Classification standard data, in which is registered image data information that is the standard when image data is classified, and classification data, in which is registered image data information that is the result when newly input image data is classified using the classification standard data, are stored in a storage unit. An image classification device is characterized in that when any image data information of the image data that is registered in the classification data is selected by means of an input unit, and an instruction to additionally register the selected image data information in the classification standard data is input by means of the input unit, the selected image data information is additionally registered in the classification standard data.
