摘要： PROBLEM TO BE SOLVED: To precisely inspect a fine pattern of a semiconductor integrated circuit or the like. SOLUTION: The image of an object having an irregular pattern is taken by an image pickup element 4 in the off-focused state. The image of the object taken in the off-focused state is read in an image processing computer 6. The image processing computer 6 forms a light intensity profile having a peak corresponding to the boundary part of the recessed part and protruding part of the irregular pattern of the object on the basis of the image. The width of the recessed part or protruding part of the irregular pattern, for example, is measured on the basis of this intensity profile, whereby the fluctuation can be extremely precisely detected.

摘要： PURPOSE:To prevent the presence of knots in the intensity distribution of exit light by specifying the thickness or width of an optical waveguide core and the refractive index of this optical material and emitting guided light of a higher mode with the unimodal intensity distribution. CONSTITUTION:A thin film 12 of Ta2O5 is formed as the optical waveguide core on a nonlinear optical crystal substrate 11 consisting of a single crystal (a) plate of KTiOPO4 (a substrate having the face orthogonal with the a-axis of the crystal as a plate face) and patterns 13 of SiO2 are loaded thereon, by which the charge type optical waveguide is formed. The refractive index of the optical material constituting the optical waveguide core 12 is set higher by >=0.1 than the refractive index of the optical material constituting the substrate 11 and thickness T or width W of the optical waveguide core 12 is set smaller than the wavelength in the air of the guided light. As a result, the light is confined and guided in the range narrower than the wavelength in the air in the optical waveguide core 12 even if the waveguide mode is a higher mode of a first order or above and, therefore, the unimodal intensity distribution free from the knots is obtd. at the time the light is emitted outside.
