摘要： PROBLEM TO BE SOLVED: To provide a simple measurement method for minutely measuring a true shape of a strip-shaped body in its entirety, the body moving at a high speed with its height varying.
SOLUTION: According to this shape measurement method of an optical cutting mode, a linear laser light source with its output modulated is used to form an optical cut image on the strip-shaped body, and a linear sensor of a delay integration type is used on the imaging side to perform overlap-imaging while shifting the cut image bit by bit, thus restoring the shape of the strip-shaped body. In this method, a widthwise position including only vibration components is searched for and a lengthwise height variation of a plate at this position is subtracted from a shape including vibration to remove the vibration, thereby measuring an original shape. Further, wave pitches are found from a change in the length of a widthwise cross-sectional curve while finding an elongation percentage from the length of a longitudinal height curve of the plate to simply calculate a wave height by sine-wave approximation.

摘要： PROBLEM TO BE SOLVED: To detect, more simply and accurately than conventionally, the size and depth of a surface flaw on a welded part from a cross-section profile of the welded part.
SOLUTION: The cross-section profile of the welded part is extracted to find the rate of change in the cross-section profile. Outermost left/right steep change parts of the welded part where the rate of change is large are taken as left/right toe parts. An inside bead part lying between the left/right toe parts is approximated and expressed by means of a first function by using cross-section profile data other than the change parts corresponding to flaw parts. A parent material part on the left-outside of the left toe part is approximated and expressed by means of a second function, while a base material part on the right-outside of the right toe part is approximated and expressed by means of a third function. The intersection of the first and second functions is found as a left toe point, while an intersection of the first and third functions is found as a right toe point. The left and right toe points, as divisional points, and a divisional approximated curve expressed by the first to third functions, as a reference line, are deducted from the original cross-section profile.

摘要： PROBLEM TO BE SOLVED: To finely measure the true shape of a strip-like body traveling at a high-speed, over the whole surface, to which fluctuation in height is added.
SOLUTION: In the shape measuring method of optical cutting type, in which a optically cut image is constructed on the strip, using a linear laser light source whose output is modulated, in which a superimposed image is captured using a delayed integration type linear sensor on the imaging side, by slightly shifting the optically cut images step by step so as to reconstruct the shape of the strip-like body, a plurality of pairs of the linear laser light sources and the linear sensors are prepared. By calculating the difference between the shapes reconstructed by each pair, and by integrating the difference, the true shape of the strip-like body traveling at a high-speed, from which the fluctuation in height due to the vertical vibration or the torsional vibration is eliminated, is finely measured over the entire surface of the strip.

摘要： PURPOSE:To reduce the size of an electric field distribution measuring instrument utilizing an electro-optic effect. CONSTITUTION:Linearly polarized light emitted form a semiconductor laser light source 1 is led to an electro-optic probe 6 through a half mirror 3, 1/8 wave plate 4, and objective lens 5 after the light is transformed to parallel rays through a collimator lens 2. Reflected light from the probe 6 is led to a double-refraction diffraction grating 8 through the lens 5, plate 4, and mirror 3. The reflected light is separated into orthogonal polarized light components through the grating 8 and the light components are made to incident to prescribed light receiving surfaces 9a, 9b, and 99c of a photoreceptor element 9. Since the grating 8 is used for separating the polarized components from each other, the separating angle of the polarized light components can be increased even when the thickness of the element 9 is not increased. In addition, since the plate 4 is arranged on the forward and backward paths of the light, the inside space of this electric field distribution measuring instrument can be effectively utilized.
