Title: Aspherical-shape measuring apparatus
Inventor: NISHIKAWA NAOYUKI
IPC: G01B11/24
Filed: 1989-11-14
Abstract: PURPOSE:To decrease errors by providing a means for scanning a surface to be mea sured in the direction of an optical axis, providing means for obtaining a position where a differential coefficient becomes zero with respect to the interference fringe obtained at each scanning position, and detecting a position where the curvature of an aspherical shape agrees with curvature of an incident spherical wave. CONSTITUTION:Coherent light outputted from a laser light source 1 is converted into parallel light through an optical system comprising a lens 2, a pinhole 3, a collimator lens 4 and the like. The light is split into two light beams through a beam splitter 5. One light beam is reflected from a reference mirror 8 and returned to the splitters as the reference light. The other light beam becomes a spherical wave through a 5 spherical-wave generating lens 6. The wave is projected on a material to be measured 7. The light reflected from the material to be measured 7 is returned to the splitter 5 as the measuring light. The light is overlapped with the reference light from the reference light 8, and interference fringes are observed on an observing plane 10. Then, the interference fringes are analyzed by a phase shifting method. A position where an aspherical shape agrees with the curvature of the incident spherical wave is obtained. The aspherical shape is obtained by using this position.

Abstract: PURPOSE:To decide a binarizing threshold level while taking preceding of a shape of a binarized image over others by surrounding a specific lightness (color) area of an object image with a closed curve, designating the lightness (color) included in the inside to entirely a white or a black level and deciding a threshold level so that the object image is binarized in a desired shape. CONSTITUTION:An area in which a white level or a black level is desired to be designated is surrounded by an enclosed curve, all picture elements in the inside are used as pointers to read the lightness (color) and to set a threshold level. In the case of a color picture, multi-value quantized values subject to A/D conversion by R, G, B color components are combined and the color is expressed in a series of number. For example, an image 1 having a contour shown in dotted lines in figure is surrounded by an enclosed curve 2 shown in solid lines along the contour and the lightness of picture elements in the inside is set to a white or a black threshold level. Since a required image is directly indicated, the setting of the binarizing threshold level in which the shape of image takes precedence over others is easily attained.
