    摘要: Film of a known refractive index whose thickness is to be measured is illuminated by a white light beam. Two wave fronts from both sides of the film are directed to an interferometer. The wave fronts are out of phase in accordance with the thickness of the film. The two wave fronts are amplitude-split, respectively, by the beam splitter of the interferometer. Two of the split wave fronts are tilted by tilting means in the interferometer. The other two split wave fronts, as well as the two tilted wave fronts, are directed to an interference surface. Thus, there is formed a white interference pattern on the interference surface. The white interference pattern has a middle peak and two side peaks. The space interval between these peaks is measured by a scanner. By knowing the peak-to-peak interval, it is possible to discriminate the space interval between both sides of the film.

    摘要: Without using an interferometer, small displacement and/or three-dimensional shape of an object is detected in a noncontact way with high accuracy using pseudo-phase information calculated from e.g., a speckle pattern having a spatially random structure. A speckle image of the test object of the before displacement is obtained, and a spatial frequency spectrum is calculated by executing an N-dimensional Fourier transform for this. The complex analytic signal is obtained by setting the amplitude of frequency spectrum in the half plane including zero frequency in this amplitude distribution to zero, and executing the frequency spectrum amplitude in the half plane of the remainder in the inverse Fourier transform. And then, the amplitude value of this complex analytic signal is replaced with the constant value, a part of the obtained analytic signal domain is clipped, the phase information is calculated by the phase-only correlation function, and the cross-correlation peak in N-dimension is obtained. The displacement magnitude can be obtained by executing the above-mentioned method to the after displacement of the test object, and obtaining the difference of the cross-correlation peak before and after the displacement.

    摘要: A three-dimensional shape measuring method by which measurement of a three-dimensional shape is realized with an improved precision. Grid patterns comprising a plurality of one-dimensional grids 1, 2 and 3, each having a period and direction different from those of the others, are simultaneously projected upon objects to be measured, using different colors for each of the one-dimensional grids 1, 2 and 3. Subsequently, a grid image deformed in accordance with the three-dimensional shapes of the objects to be measured is imaged, the grid image is separated by colors into one-dimensional grid components of each color, a phase for each of the one-dimensional grid components is detected, and then, measurement values of the three-dimensional shapes are obtained on the basis of the detected phases. At the same time, by imaging the objects to be measured by use of white light, color information on the objects to be measured are measured as well.
